描述.This book addresses a broad community of physicists, engineers, computer scientists and industry professionals, as well as the general public, who are aware of the unprecedented media hype surrounding the supposedly imminent new era of quantum computing. The central argument of this book is that the feasibility of. .quantum computing in the physical world is extremely doubtful. The hypothetical quantum computer is not simply a quantum variant of the conventional digital computer, but rather a quantum extension of a classical .analog. computer operating with continuous parameters. In order to have a useful machine, the number of continuous parameters to control would have to be of such an astronomically large magnitude as to render the endeavor virtually infeasible. This viewpoint is based on the author’s expert understanding of the gargantuan challenges that would have to be overcome to ever make quantum computing a reality. Knowledge of secondary-school-level physics and math will be sufficient for understanding most of the text..

Basics of Quantum Mechanics,The basic ideas of Quantum mechanics are presented in a somewhat simplified form, hopefully understandable to some extent by general readers.

Related Issues and Conclusions,While mathematics is indispensable for understanding the physical world, there are many ways of abusing mathematics, and some examples are presented. Sociological issues related to the saga of quantum computing are briefly discussed.

Brief History and Overview of the Main Ideas for Quantum Computing,actoring algorithm. In this chapter, the main theoretical ideas and terminology of quantum computing are briefly presented. The frightening statement, commonly used by journalists that the qubit can be in two different states at the same time, is demystified.

The Theoretical Quantum Computer and the Physical Reality,nalysed. In mathematics, one proves theorems on the basis of axioms, which by definition are supposed to be fullfilled exactly. However, in the physical world nothing can be exact. The existing theory does not respond to the obvious question: what precision is needed?

More Problems with Quantum Computing,all qubits are exactly equal, which is hadrly possible. Otherwise, there will be a free evolution of the system defined by its energy spectrum. Also it is still not possible to factor the number 15 by Shor’s algorithm, and error correction is still non-existant.
