Quantum computation and quantum communication: theory and experiments Author of book: Mladen Pavicic
Review of1 Quantum Computation and Quantum Communication: Theory and Experiments Author of book: Mladen Pavicic 239 pages, Springer, $88.00 Author or Review: George Hacken Introduction Though post-relay and post-vacuum-tube digital computers are Âquantum  in the sense that Quantum Mechanics underlies solid-state (in particular, semiconductor) physics, Quantum Computing could, with my apologies to quantum Âeld theorists, fairly be characterized as Computing Âs Âsecond quantization.  Pavicic Âs book achieves its own characteristic balance between the complementary attributes, depth and breadth, such that algorithmists and computation theorists will be reading both within and very much around their subject as that subject is conventionally construed. (James D. Watson advises in his recent book2 that we should indeed Âread around  our subject.) The book Âs preface states that Âthe theory of the Âeld leads the experiments in a particular way . . . . As a consequence, both mathematics and physics are equally essential for any approach in [sic] the Âeld and therefore for this book as well.  Quantum Computation and Quantum Communication is subtitled Theory and Experiments; it comprises three chapters: Chapter 1, Bits and Qubits, is an explication of computation-theory as c 2009 George Hacken Avoid Boring People, Random House, 2007 ACM SIGACT News December 2009, vol. 40, no. 4 built up from, and related to, states that are quantum-mechanical ( Âcoherent Â) superpositions of 0s and 1s, these latter being construed as quantum-mechanical Hilbert-space basis states (qubits) |0 > and |1 > that are subject to Cartesian-product juxtaposition for the case of higher dimensions. Chapter 2, Experiments, is a substantial enumeration of evidence for, and possibilities of, realizable quantum computers. Chapter 3, Perspectives, is a synthesis and...
