Time travel: Light speed results cast fresh doubts
26 July 2011 Last updated at 05:46 ET
Physicists have confirmed the ultimate speed limit for the packets of light called photons - making time travel even less likely than thought.
The speed of light in vacuum is the Universe's ultimate speed limit, but experiments in recent years suggested that single photons might beat it.
If they could, theory allows for the prospect of time travel.
Now, a paper in Physical Review Letters shows that individual photons too are limited to the vacuum speed limit.
That means that photons maintain the principle of causality laid out in Einstein's theory of special relativity - that is, an event's effect cannot precede its cause by traveling faster than light. It is violation of this causality that would, in principle, permit time travel.
While the limit in vacuum is a fixed number - some 300,000km per second - the speed of light can vary widely in different materials.
These differences explain everything from why a straw looks bent in a glass of water to experiments in cold gases of atoms in which light's speed is actively manipulated.
Some of those experiments showed "superluminal" behaviour, in which photons travelled faster than the speed of light in a given medium.
It remained, however, to determine whether or not individual photons could exceed the vacuum limit.
Now, Shengwang Du and colleagues at the Hong Kong University of Science and Technology have measured what is known as an optical precursor.
Like the wind that moves ahead of a speeding train, optical precursors are the waves that precede photons in a material; before now, such optical precursors have never been directly observed for single photons.
By passing pairs of photons through a vapour of atoms held at just 100 millionths of a degree above absolute zero - the Universe's ultimate low-temperature limit - the team showed that the optical precursor and the photon that caused it are indeed limited to the vacuum speed of light.
"By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon," said Professor Du.
Thus, photons cannot time travel, and moving information around at faster-than-light speeds is impossible.
But the work has more prosaic implications.
"Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information," said Professor Du.
Time travel by other means, however, is not entirely ruled out.
Einstein's theory of general relativity, in which space and time are two intertwined aspects of the same medium, would permit the bending of the medium to join two different times - a situation popularised as creating a "wormhole".

Almost 800 Attend ZOA Dinner - Media Superstar Glenn Beck, House Foreign Relations Chair Ros-Lehtinen, Cong. Michele Bachmann & PM Netanyahu Spoke
November 21, 2011
FOR IMMEDIATE RELEASE
Contact: Dr. Michael Goldblatt
U.S. Rep. Michele Bachmann,
Adelsons and Six Congressmembers Attended
Jim Tisch and Martin Gross Co-Dinner Chairs
NEW YORK Almost 800 people attended the Zionist Organization of America's (ZOA) 114th Louis B. Brandeis Award National Dinner on Sunday, November 20 at the New York City's elegant Grand Hyatt Hotel. Media superstar and seven-time NY Times best-selling author Glenn Beck, U.S.Congresswoman and House Foreign Relations Committee Chair, Rep. Ileana Ros-Lehtinen (R-FL) were keynote speakers at the Dinner at which they were also honored. Mr. Beck was awarded the Dr. Miriam & Sheldon Adelson Defender of Israel Award. U.S. Cong. Michele Bachmann (R-MN) and Israeli Prime Minister Netanyahu also spoke. Prominent philanthropists Dr. Miriam and Sheldon Adelson spoke and personally presented the Adelson Award to Beck.
U.S. Cong. Ann Marie Buerkle and Robert Turner from NY, Cong. Dan Burton from Indiana and Cong. Joe Walsh from Illinois also attended the Dinner; other prominent guests included Richard Stone, Chair of the Conference of Presidents of Major American Jewish Organizations and Steve Emerson, terrorism expert. Rep. Ros-Lehtinen was awarded the Dr. Irving and Cherna Moskowitz Award. William K. Langfan and Mark Langfan, prominent lawyers and real estate entrepreneurs were honored with the Louis B. Brandeis Award. Jerome & Judy Taylor, distinguished philanthropists, received the Maccabee Award.
In his video address to the Dinner guests, Prime Minister Netanyahu spoke of the "remarkable and important ZOA." ZOA's "courage and integrity" which, he observed, under Mort Klein's leadership, had been "absolutely fearless" in fighting for the truth and working to advance the cause of Israel with the government, media and the American public. Mr. Netanyahu said, in these times of "seismic changes across the Middle East," the ZOA had been "unflinching" in its advocacy for which "I want to thank you from the bottom of my heart." "I also want to congratulate Glenn Beck for winning the Adelson Defender of Israel Award. If Dr. Miriam and Sheldon Adelson put their name on something, it must stand for a lot." Netanyahu said. "Glenn
you stand for a lot. You too have been fearless in defending Israel against the slanders that are hurled against [it]. You've done that with considerable personal cost, but you've never backed off, you've never flinched, you've never walked away. And I want to tell you how deeply we appreciate this stand of courage and integrity." Prime Minister Netanyahu also strongly praised Ileana Ros-Lehtinen, and Miriam and Sheldon Adelson s long-time and powerful supporters of Israel.
ZOA Board Member Harvey Friedman introduced Rep. Ros-Lehtinen, describing her as a "national treasure to every Jew in the U.S." and describing her legislative efforts opposing U.S. funding of both Mahmoud Abbas' Palestinian Authority (PA) and the United Nations Relief and Works Agency (UNRWA). Rep. Ros-Lehtinen came to the podium and was greeted with a standing ovation. In her address, Rep. Ros-Lehtinen commenced by saying that she was "proud to be associated for so many years with ZOA." She spoke of two Dinner attendees, residents of the Jewish community of Kedumim in Samaria, stating sarcastically that "they're an impediment to peace, because they live in the Judean & Samarian community of Kedumim." Turning to the Iranian threat, Rep. Ros-Lehtinen said that the Obama Administration's policy for stopping Iran had been completely ineffective - "all we've got is a further three years closer to Iran getting a nuclear bomb." She called for further U.S. action, including genuinely "crippling sanctions to help bring this regime down
We passed the sanctions bill [H.R. 1905] targeting Iran's Central Bank." Speaking of the U.N. Reform, Transparency and Accountability Act [H.R. 2829], an earlier law which the Congress had passed that cuts funds to UN agencies that raise the states of the Palestinians, Rep. Ros-Lehtinen recounted how the Obama Administration had sought "flexibility" in its application, to which she had retorted with emphasis that "no flexibility" on the law would be allowed. She also referred to the views of the Obama Administration and Palestinian apologists before pausing and adding, "Did I repeat myself?"
Israeli scholar and director of the Begin-Sadat Center for Strategic Studies at Bar-Ilan University, Professor Efraim Inbar, presented the Louis B. Brandeis Award to William K. Langfan and Mark Langfan. Inbar said, "Bar-Ilan University is the only Zionist university left in Israel," saying that Tel Aviv University and the Hebrew University in Jerusalem, for example, were "not Zionist" in his opinion. "There are many Bolshevik post-Zionists at these universities, who pack their faculties with similar-minded lecturers. The Israeli universities are overflowing with post-Modernists who undermine not only Zionism but academic truth itself."
Inbar said that although he knows that there are also Zionist lecturers at the various Social Studies faculties, they are outnumbered. "An evil wind is emanating from these places," he said.
ZOA National Chairman of the Board, Dr. Michael Goldblatt delivered the presentation to Maccabee Award recipients Judy and Jerome Taylor, noting that they had been "long-time pro-Israel activists" who had worked side by side for years on behalf of Israel. He also noted that Judy Taylor's father had been involved in prosecuting Nazi war criminals at the Nuremberg war crime trials, so that working "to protect Jews was in her genes."
ZOA National President Morton Klein introduced U.S. Rep. Michele Bachmann of Minnesota, observing that, while many speak of the importance of Israeli security, all too few speak of "the sacredness of the land of Israel. "If security was the entire issue for Israelis, they should move to Minnesota, it's safer there." That's why we're there. While noting that the ZOA does not endorse any political candidates, Klein described Rep. Bachman as "dynamic, principled and committed to her beliefs." Rep. Bachman opened by describing herself as a lover of Israel. "Although I'm not a Jew, I'm a Christian, we have something in common, the book of Genesis, which states that `Those who bless Israel will be blessed and those that curse Israel will be cursed.' I stand with Israel."
She said her first foreign policy directive on Day 1 of her presidency would be moving the U.S. embassy to Israel from Tel Aviv to Jerusalem. The Palestinians "must recognize Israel's right to exist and renounce violence" if they expect to become a serious partner for peace. and that, under current conditions, Israel should cede to the Palestinians "not one acre, not one square foot, not one inch." She chastised President Obama for failing to support Israel, saying, "President Obama stands with Occupy Wall Street, but he doesn't stand with Israel. When Israel looks at President Obama, they don't see a friend." The United States "must sell Israel the additional fighter jets, bunker buster bombs, refueling tankers, and other materials they need to defend themselves," she said. She also said the United States should continue its "comprehensive missile system" in the Middle East. Rep. Bachman also spoke of the existential threat posed by Iran to both Israel and the U.S., declaring that the "Pentagon should prepare a war plan as a last resort, should all else fail in preventing Iran from getting nuclear weapons." She said that, while "only a fool wishes for war," other steps, like but a naval blockade of Iranian ports, increased intelligence operations against Iran and "crushing economic sanctions" were adequate the gravity of the threat. She called on President Barack Obama "to accelerate covert operations and cyber operations in Iran and order the CIA Director to take all means necessary to stop Iran from getting the Bomb before it is too late." Asserting that Iranian President Ahmadinejad was "striving for a second Holocaust" Bachman said that "once again millions of Jews are at the precipice of losing their lives today". Ahmadinejad, she said, "will seek to use nuclear weapons against the US as well and the US will learn what it is to be Israel if it does not act quickly." She said that the US Secretary of Defense, Secretary of State and CIA director must all support this "freedom policy" and that those in the bureaucracy who fail to do so "especially in the State Department" should be replaced.
ZOA Vice-Chairman of the National Board Steve Goldberg introduced Morton Klein pointing out that "Without Mort, there would be no ZOA. Mort rescued it when it was moribund .. Your shoes are too big and cannot be filled ... all the ZOA's past leaders, including Louis Brandeis and Abba Hillel Silver pale in comparison to Mort Klein."
Mort Klein commenced his address by praising Christian Zionists for their heartfelt support of Israel, especially at a time Israel has few reliable friends. "We applaud Christian Zionists, thank G-d for you ... People forget that Israel is called the Promised Land for a reason - because it was promised to the Jewish people by G-d." He emphasized that, unlike several other Jewish organizations, the ZOA was active in bringing Jewish students , not just to Israel, but specifically also to Jewish communities in Judea-Samaria like Efrat, Gush Etzion, Maale Adumim, Hebron, Ariel, and so on.
Klein spoke of the ZOA Law and Justice Center, headed by Susan Tuchman, and its important breakthrough in having Title VI of the Civil Rights Act, which has applied to blacks and Hispanics, now applied to protecting Jewish students from discrimination, intimidation and harassment. He noted that the Office of Civil Rights would be investigating incidents involving Jewish students at Rutgers University.
In his remarks, Klein criticized Abe Foxman of the Anti-Defamation League and David Harris of the American Jewish Committee for their strong opposition to an Israeli bill on sovereign foreign countries providing millions of dollars to anti-Israel non-governmental organizations that operate in Israel under the guise of being human rights organizations.
Turning to the Arab war on Israel, Klein observed that "the Arab war against Israel has nothing to do with borders, land, settlements or a Palestinian state. It is simply old-fashioned Jew- hatred and anti-Semitism. The Arabs don't want a Jewish state within any borders. Please understand, Arabs don't want peace with the Jewish state, they never wanted peace with the Jewish state. And as much as we want peace, Israel will live and thrive without it as it has since 1948." Klein also noted that the world was silent on the fact that Hamas, with which Mahmoud Abbas' PA had signed earlier this year a unity government agreement and with whose leader, Khaled Meshaal, Abbas had met earlier in the week, calls in Article 7 of its Charter for the global murder of Jews - "This is a Nazi document, these are Nazi terrorists" and, to show that Fatah is similar, Klein held aloft the Fatah emblem, encompassing all of Israel under a Palestinian kfiyyeh, with a picture of arch-terrorist Yasser Arafat and a Kalashnikov rifle.
Klein continued, "The PA has violated the three legs of the Oslo accords. The PA has not stopped terrorism, has not accepted Israel's right to exist, and refuses to stop anti-Israel incitement. Why are U.S. officials and Israeli officials not speaking out against this in our serious manner. We should be telling the PA- no more money, no more support, no more concessions. People speak as though a Palestinian state was the solution. It isn't. Iran, Syria, North Korea - they're all states, but that hasn't made them lovely and peaceful. In fact, it gives them more power to advance their terrible agenda. American Jews are now understanding this for the first time since Oslo, a majority of American Jews oppose establishing a Palestinian state." In a blistering attack on the Palestinians and on U.S. policy, Klein listed unjust accusations hurled against Jews since the time of the Crucifixion, drawing parallels to the current situation of Israel and the Jews and summing up with a sentence that seemed to encapsulate the attitude of most of the evening's participants: "The whole world is wrong, and the Jews are right." Klein received a standing ovation.
Sheldon Adelson and Dr. Miriam Adelson, stalwart supporters of ZOA and recipients of its rarely bestowed Theodor Herzl Gold Medallion and Brandeis Award respectively, introduced keynote speaker Glenn Beck. Mr. Adelson said first of Mort Klein that "I used to think that my wife was the strongest Zionist until I met Mort. He's my Zionist mentor. He's the greatest and most passionate Zionist, not only in this country but in the world." In introducing Mr. Beck, Mr. Adelson described him as a "very special man .... We knew he was a giant even before we met him. I'd never known a Christian Zionist like Glenn Beck. Glenn Beck tells the truth about the Arab war against Israel." Adelson, also the publisher of Israel Hayom (now Israel's largest daily newspaper), added there is "no greater supporter of Israel in the media today" than Beck. When Palestinians murdered five members of the Fogel family in last March's Itamar massacre, Beck dedicated an entire show on Fox News to the tragedy and "displayed the pictures that almost every other television network ignored" Palestinians celebrating the event by handing out candles in the streets Adelson said.
Glenn Beck came to the podium amid a standing ovation and commenced his address with the words, "Well, this isn't going to help my popularity with the media .. I am a proud Christian Zionist. I know what that means in today's world. But I put all my chips on the table. Is there a G-d? And if so, how shall I serve Him? The whole world is in the middle of a profound and dramatic change, but the change need not be bad. History is calling us now." Beck talked about the danger facing Jews because today the world is "aiding and abetting" the ranting of many madmen who are out to destroy Israel and the Jewish people. He pledged to announce on December 8 where he is headed "there is a vacuum and I intend to stand in its place," he said but gave no details as to what he was referring to. Beck said, "Many times you cannot tell the difference any more between peace activists and the terrorists and fascists they claim to stand against." Mr. Beck reflected on the eight years since he had first gone to Israel and the evolution of his understanding of the country, and how few genuine friends it has, joking, "This is what bad shape things are in, you've got me."
Speaking of the numerous individuals and groups working actively against Israel and the Jewish people, Mr. Beck said that "It's a badge of honor to be called an enemy of George Soros. Soros is not a friend of Israel and, let me say, neither is the Administration. But let me tell you we, the people of the United States are not the government, we are a country built on the individual, not on the government."
Mr. Beck cast his mind back to several predictions and warnings he has given over the past decade and how he had been looking for what he called the "Archduke Ferdinand moment," referring to the assassination of Austrian Archduke Franz Ferdinand which had triggered World War One. "I spoke of a coming caliphate. I was ridiculed. I even once put it up on a chat on my program, saying `This is what is coming' ... It will get worse if we don't stand together now. We must stand with Israel ... Jerusalem must remain Israel's "united and undivided capital ... I don't come here as a Christian. I come here as a brother. Evil hates you. It has since the beginning of time. Evil thinks it can somehow force G-d to break his covenant and that it can destroy the Jewish people. Israel wasn't established because of the Holocaust. That's just the last time such an attempt was made. Israel was promised by G-d to the Jews." Mr. Beck pledged to continue his work to speak the truth and to arouse the conscience of his listeners and was given a tumultuous standing ovation.
This year, a record number of college students - well over 100 - attended the Dinner. James A. Tisch, former Chairman of the Conference of Presidents of Major American Jewish Organizations and NY Jewish Federation, and CEO of Loews Corp.; and Martin Gross, President of the Washington Institute for Near East Policy and Member of the Board of Trustees of Brandeis University, were Dinner Co-Chairmen. Rabbi Mark Wildes, director of the Manhattan Jewish Experience, delivered the invocation. ZOA Executive Director David Drimer and the entire ZOA staff worked hard on all aspects of the Dinner and Dr. Alan Mazurek, Chairman of the ZOA's National Advisory Council, was Master of Ceremonies, presiding over proceedings with his usual aplomb and elegant wit.

Atoms entangled using microwaves for first time
Posted on August 11, 2011 - 04:59 by Kate Taylor
NIST physicists have for the first time linked the quantum properties of two separated ions by manipulating them with microwaves instead of the usual laser beams.
The development could mean that the usual room-sized quantum computing 'laser park' could be replaced with miniaturized, commercial microwave technology similar to that used in smart phones.
Microwaves have been used in the past to manipulate single ions. But positioning microwaves sources close enough to the ions allows entanglement - a quantum phenomenon expected to be crucial for transporting information and correcting errors in quantum computers.
The team integrated wiring for microwave sources directly on a chip-sized ion trap, and used a table of lasers, mirrors, and lenses that is only about one-tenth of the size previously required.
"It's conceivable a modest-sized quantum computer could eventually look like a smart phone combined with a laser pointer-like device, while sophisticated machines might have an overall footprint comparable to a regular desktop PC," says NIST physicist Dietrich Leibfriedr.
"These components are well developed for a mass market to support innovation and reduce costs. The prospect excites us."
Quantum computers would harness the unusual rules of quantum physics to solve certain problemssuch as breaking today's most widely used data encryption codesthat are currently intractable even with supercomputers. A nearer-term goal is to design quantum simulations of important scientific problems, to explore quantum mysteries such as high-temperature superconductivity, the disappearance of electrical resistance in certain materials when sufficiently chilled.
The use of microwaves reduces errors - but the technique needs to be improved to enable practical quantum computations or simulations. The NIST researchers achieved entanglement 76 percent of the time, well above the minimum threshold of 50 percent defining the onset of quantum properties, but not yet competitive with the best laser-controlled operations at 99.3 percent.See more about:

Physicists Entangle Atoms Using Microwaves for the First Time
K. Cameron Lau | Aug 11, 2011 | 2min:32sec Physicists Entangle Atoms Using Microwaves for the First Time. Physicists at the National Institute of Standards and Technology have for the first time linked the quantum properties of two separate ions by manipulating them with microwaves instead of the usual laser beams.

Quantum super-computing sees microwave breakthrough
(AFP) 23 hours ago
PARIS Physicists in the United States on Wednesday notched up a lab success in the quest for quantum computers, whose stellar capacities have already earned them the nickname of "super-computers on steroids."
Atoms can be excited to a quantum condition using microwaves, an advance over larger and bulkier lasers, until now the only way to achieve this essential state, they said.
In theory, it means that quantum computers -- if they are commercially feasible -- could be as tiny as a small book, the team reported in Nature, the British science journal.
"It is conceivable a modest-sized quantum computer could eventually look like a smart phone combined with a laser pointer-like device," said Dietrich Leibfried of the US National Institute of Standards and Technology (NIST).
"Sophisticated machines might have an overall footprint comparable to a regular desktop PC."
The idea behind quantum computing is to exploit a weird discovery of particle physics.
When two particles interact, they become "entangled," which means one particle affects the other. The connection lasts long after they are separated.
In "entanglement," particles also go into state called superposition.
Today's computers use a binary code, in which data is stored in a bit that could be either zero or 1.
But in superposition, a quantum bit, known as a qubit, could be either zero or one, or both zero and one at the same time.
This potentially offers a massive increase in data storage, greatly help ing number-crunching tasks such as running climate-change models and breaking encrypted codes.
In the new experiments, NIST physicists held two electrically-charged atoms, also called ions, of magnesium in a "trap" of electro-magnetic fields.
The ions hovered just above a chip consisting of gold electrodes, some of which were activated to create targeted pulses of microwave energy in the one to two gigahertz range.
The microwaves produced minute magnetic fields to manipulate the spin of the ions so that they reached entanglement.
The scientists hit the spot 76 percent of the time, above the threshold of 50 percent considered to define the onset of quantum properties, thus providing solid proof that microwaves work.
But it was still well short of the best laser-controlled operations, which stand at 99.3 percent, indicating that many improvements remain.
Lasers are still needed in the new technique, for low-powered ultraviolet lasers kept the ions cool and were used to measure the results.
But -- again, if many practical hurdles are overcome -- this should not be a problem for miniaturising the quantum computer of the future, say the scientists.
In a commentary also published in Nature, Winfried Hensinger of Britain 's Sussex University hailed the achievement as "step-changing innovations."
"Quantum computing is likely to revolutionise many areas of science, and we have only just started to appreciate its true potential."

Ion Teleportation Scheme Could Scale Up Quantum Computers By Saswato Das
First Published January 2009
Scientists have teleported the quantum state of one trapped ion onto another a meter away
23 January 2009A team of scientists is announcing today in the journal Science that in one of those bizarre demonstrations of quantum mechanics it has managed to teleport the quantum state of one ion onto another across a distance of a meter. Though we're accustomed to thinking of the Star Trek version of teleportation, what physicists call teleportation is the exact mapping of one particle's quantum characteristics to another distant particle. That matters because future quantum computers <http://www.spectrum.ieee.org/aug07/5378
> and quantum cryptography networks <http://www.spectrum.ieee.org/oct08/6919
> need some way of storing data and moving it around.
In the past decade, physicists have shown that teleportation is possible with magnetic fields, photons, and even atoms. What makes the new resultsby Christopher Monroe of the University of Maryland and his colleaguesinteresting is that the team uses a hybrid approach involving both atoms and photons that fits well with quantum information networks and quantum computers. Theoretically, Monroe says, the technique they have invented can be extended to distances as great as thousands of kilometers, although all they have demonstrated so far is one meter.
Raymond Laflamme, director of the Institute for Quantum Computing, at the University of Waterloo , in Canada , called it "a very neat experiment and important milestone, demonstrating very good quantum control and bringing quantum teleportation one step nearer to practical applications."
At the heart of teleportation lies a quantum mechanics effect known as entanglement. That phenomenon allows two particlessuch as photons, atoms, or ionsto be linked in such a way that if someone measures the quantum state of one object, the state of the other becomes known as well. Entangled photons are often used in experimental quantum information networks. But while photons are easy to transmit (after all, they move with the highest speed in the universe), they are very difficult to store <http://www.spectrum.ieee.org/dec08/7084
>. On the other hand, atoms and ions preserve entanglement for a long time, but being massive, they are much harder to move from place to place.
The beauty of Monroe 's approach to teleportation is that it is an intelligent combination of the strengths of photons and ions. His team used two ytterbium ions confined in electromagnetic ion traps and cooled by lasers. The goal is to teleport the quantum state of one ytterbium ion to the other. Both ions are prepared for entanglement by microwave pulses and then zapped by ultrafast laser pulses. Each ion subsequently gives off a photon, which is entangled with the ion's state. Through a complex series of steps, the system transfers the quantum state of one ytterbium ion to the other.
Norbert Lütkenhaus, of the Institute for Quantum Computing, says Monroe 's approach "make sense." He says that "this technique allows them to couple ion traps in this optical way."
Monroe says the hybrid approach will enable the creation of quantum repeatersstill-theoretical devices needed to make large-scale quantum cryptography networksand will also be useful for making quantum computers. His group's design for scalable quantum computers is to build multiple ion traps on a chip. The ions act as quantum bits and can perform computations when placed close together in a trap. However, to get the result of one trap to a computation in another trap without some sort of teleportation would require the difficult task of moving ions around on the chip. He says teleportation "may well be the most scalable approach" to building ion-chip computers.
Dick Slusher of the Georgia Tech Research Institute, isn't so sure. "I think that in principle it is true that this teleportation process will facilitate scaling of quantum computation," he says. "However, there are many ways to accomplish this scaling, including ion transport and error-correcting pulse sequences. Teleportation may well turn out to be the key process for scaling, but I think it is far too early to be sure of this."

We may walk around the area-there are a lot of Jewish shops and restaurants here, although many may be closed on a Saturday night after Shabbat.
If there is some snow on the ground, the Secaucus hikes will be cancelled and we will meet at 10:00 at Losen Slote Creek Park and spend the whole day there and Pascack Brook County Park. I will call the park rangers the day before to see how things are going and listen to the weather forecast. Also, the Secaucus hikes are adjacent to the enormous Secaucus Outllet Shopping District and I may cancel the Secaucus hikes if I am told that the crowds and traffic are too enormous and brutal.
This is a kid friendly event. Come for as much of the day as you want. If you are coming for part of the day, please let me know when to expect you. Dress in layers. Bring with you: water, lunch, snacks and hiking boots). If it is too cold out, we may be eating in the food court of the mall. If you are coming by public transportation, please let me know. We will drive you from place to place and you will be able to take the bus back from Chickies Kosher French Fry & Chicken Bar. Do not buy a round trip ticket. You will be going back to NY on a different bus! As always, there is a $5 nonmember/unpaid member fee.

Giant leaps keep on happening. Interesting that the quantum leap, (pun intended), was announced on the anniversary of another giant leap.
One small step for man, one giant leap for mankind
On July 20, 1969, the human race accomplished its single greatest technological achievement of all time when a human first set foot on another celestial body.
Six hours after landing at 4:17 p.m. Eastern Daylight Time (with less than 30 seconds of fuel remaining), Neil A. Armstrong took the "Small Step" into our greater future when he stepped off the Lunar Module, named "Eagle," onto the surface of the Moon, from which he could look up and see Earth in the heavens as no one had done before him.
He was shortly joined by "Buzz" Aldrin, and the two astronauts spent 21 hours on the lunar surface and returned 46 pounds of lunar rocks. After their historic walks on the Moon, they successfully docked with the Command Module "Columbia," in which Michael Collins was patiently orbiting the cold but no longer lifeless Moon.
It is wonderful that AT&T Labs is doing this:
Breakthrough removes major hurdle for quantum computing
By Chris Jablonski | July 20, 2011, 3:02pm PDT
Researchers announced that they've managed to predict and suppress environmental decoherence, a phenomenon that has been described as a "quantum bug" that destroys fundamental properties that quantum computers would rely on.
Credit: E8 Album HQR Initiative
Decoherence is the tendency of atomic-scale particles to get quickly tangled up with the larger physical world we live in. Electrons, for instance, obey the laws of quantum physics and can therefore be in two places at once, like a coin simultaneously showing heads and tails. Scientists refer to this as state superposition. In contrast, larger, more complex physical systems appear to be in one consistent physical state because they interact and "entangle" with other objects in their environment and "decay" into a single state. The resultant decoherence is like a noise or interference that knocks the quantum particle, in this case the electron, out of superposition.
The realization of quantum computing's promise depends on switches that are capable of state superposition. Until now, all efforts to achieve such superposition with many molecules at once were blocked by decoherence.
By using high-magnetic fields, researchers at University of British Columbia and University of California Santa Barbara discovered a way to reduce the level of the noises in the surroundings so they can constrain the decoherence efficiently.
"For the first time we've been able to predict and control all the environmental decoherence mechanisms in a very complex system, in this case a large magnetic molecule called the `Iron-8 molecule,'" said Phil Stamp, UBC professor of physics and astronomy and director of the Pacific Institute of Theoretical Physics. "Our theory also predicted that we could suppress the decoherence, and push the decoherence rate in the experiment to levels far below the threshold necessary for quantum information processing, by applying high magnetic fields."
The findings, which are published in today's edition of the journal Nature, could help pave the way for the development of quantum computers that perform complex calculations that are magnitudes greater than compared to today's traditional computers.

Breakthrough in quantum computing: Resisting 'quantum bug'
July 20, 2011
Scientists have taken the next major step toward quantum computing, which will use quantum mechanics to revolutionize the way information is processed.
Quantum computers will capitalize on the mind-bending properties of quantum particles to perform complex calculations that are impossible for today's traditional computers.
Using high magnetic fields, Susumu Takahashi, assistant professor in the USC Dornsife College of Letters, Arts and Sciences, and his colleagues managed to suppress decoherence, which is one of the key stumbling blocks in quantum computing.
"High magnetic fields reduce the level of the noises in the surroundings, so they can constrain the decoherence very efficiently," Takahashi said. Decoherence has been described as a "quantum bug" that destroys fundamental properties that quantum computers would rely on.
This research will appear in the online version of Nature magazine on June 20.
Quantum computing uses quantum bits, or qubits, to encode information in the form of ones and zeros. Unlike a traditional computer that uses traditional bits, a quantum computer takes advantage of the fact seemingly impossible fact that qubits can exist in multiple states at the same time, which is called "superposition."
While can a bit can represent either a one or a zero, a qubit can represent a one and a zero at the same time due to superposition. This allows for simultaneous processing of calculations in a truly parallel system, skyrocketing computing ability.
Though the concepts underpinning quantum computing are not new, problems such as decoherence have hindered the construction of a fully functioning quantum computer.
Think of decoherence as a form of noise or interference, knocking a quantum particle out of superposition robbing it of that special property that makes it so useful. If a quantum computer relies on a quantum particle's ability to be both here and there, then decoherence is the frustrating phenomenon that causes a quantum particle to be either here or there.

The researchers calculated all sources of decoherence in his experiment as a function of temperature, magnetic field, and by nuclear isotopic concentrations, and suggested the optimum condition to operate qubits, reducing decoherence by approximately 1,000 times.
Qubits in his experiment lasted about 500 microseconds at the optimum condition ages, relatively speaking.
Decoherence in qubit systems falls into two general categories. One is an intrinsic decoherence caused by constituents in the qubit system, and the other is an extrinsic decoherence caused by imperfections of the system, for example, impurities and defects.
In their study, Takahashi and his colleagues investigated single crystals of molecular magnets. Because of their purity, molecular eliminate the extrinsic decoherence, allowing researchers to calculate intrinsic decoherence precisely.
"For the first time we've been able to predict and control all the environmental decoherence mechanisms in a very complex system in this case a large magnetic molecule," said Phil Stamp, UBC professor of physics and astronomy and director of the Pacific Institute of Theoretical Physics.
Using crystalline molecular magnets allowed researchers to build qubits out of multiple quantum particles, rather than a single quantum object the way most proto-quantum computers are built at the moment.
"This will obviously increase signals from the qubit drastically, so the detection of the qubit in the molecular magnets is much easier," Takahashi said.
Takahashi conducted his research as a project scientist in the Institute of Terahertz Science and Technology and Department of Physics at the University of California Santa Barbara and analyzed the data while at UCSB and USC. Takahashi has been in the USC Dornsife College since 2010.
Research for the article was performed in collaboration with Phil Stamp and Igor Tupitsyn of the University of British Columbia, Johan van Tol of Florida State University, and David Hendrickson of UC San Diego.

A BREAKTHROUGH IN MAKING QUANTUM COMPUTING POSSIBLE?
Science fiction may be closer to science fact
July 21, 2011
(NATIONAL) -- An aspect of computing that not long ago would have been considered the stuff of science fiction may now be much closer to realty than ever.
For years scientists have been trying to figure out a way to use quantum mechanics the essence of all matter so tiny the human eye may never see them at work to build computers that are much more powerful and far smaller than today's computers.
Now researchers at the University of British Columbia and University of California Santa Barbara say they have figured out a way to predict and suppress "environmental decoherence," a phenomenon that has been described as a "quantum bug" that destroys the basic properties that quantum computers would rely on, says a report in zdnet.com
Decoherence is the tendency of tiny atomic-scale particles to get quickly tangled up with the larger physical world we live in.
Strange as it seems, electrons, for instance, obey the laws of quantum physics and can therefore be in two places at once -- like a coin simultaneously showing heads and tails. This is called a state superposition. Objects in our larger physical world cannot do that although we are all made of "star stuff" than do such a thing at level of the very tiny.
The larger, more complex physical systems human beings, fishing poles, cats and dogs, Mount Rushmore - appear to be in one static, consistent physical state because they interact and "entangle" with other objects in their environment and "decay" into a single state.
The resultant decoherence is like a noise or interference that knocks the quantum particle - in this case the electron - out of superposition.
So to do quantum computing, what are needed are switches, in a manner of speaking, capable of "state superposition," and until now all efforts to achieve such superposition with many molecules at once were blocked by decoherence.
Confused? So are we. Read the full report here `
UBC scientists announcing "major advance" in quantum computing research
By Scott Simpson 20 Jul 2011
Researchers at University of B.C. announced Wednesday that they've made a major advance in dealing with one of the biggest obstacles to development of a radical new kind of computer.
In a paper published online today by Nature, the world's top research journal, researchers at UBC and University of California Santa Barbara announced they've found a way to deal with decoherence - the tendency of atomic-scale particles to get quickly tangled up with the larger physical world we live in. Their work opens up a whole new area for researchers who are investigating the potential for development of quantum computers.
In an interview, UBC physics professor Phil Stamp said the university published a theory in 2006 that pointed to the solution and the Santa Barbara researchers found a way to make it work in a lab.
Particles such as electrons don't have to play by the same rules we do when they're moving around in the quantum-scale universe - a universe with some peculiar rules that seem to defy common sense, like being in two places at once.
