%T "Approaching Quantum Computing"

Chapter one introduces some of the basic concepts in quantum

computation, using some of the physics behind both computing and

quantum mechanics, and illustrating these ideas using experiments with

photons. The basic mathematics behind quantum mechanics is outlined

in chapter two. The second half of the chapter explains the

experimental evidence for the dual particle/wave nature of photons

leading to the requirements for theories of quantum physics, and the

historical development of quantum theories in the first half of the

twentieth century. Qubits are the data representation and processing

units of quantum computer systems. Chapter three reviews the required

characteristics for qubits, and notes a couple of physical entities

that can be used for this purpose. Gates and circuits that can be

created with quantum technologies are outlined in chapter four.

Chapter five notes the possibility of a quantum Turing machine which

may be more powerful than classical Turing machines. The material

also examines various algorithms proposed for use with quantum

computers. However, the possible limitations of quantum computing are

noted: most quantum algorithms require dedicated (rather than general

purpose) circuits, and quantum computing algorithms may be limited to

a very select class of problems (a great many of the suggested

algorithms are based on quantum Fourier transforms). Most of chapter

six details historical examinations of quantum physics. The tidbits

are fascinating, and have some bearing on quantum computing and

communications, but are poorly related to the other content of the

book.

While an academic textbook, with a heavy emphasis on abstruse

mathematics, this work could be heartily recommended to a great many

people who *think* they know something about quantum computing.
