Résumé:

Quantum computing relies on processing of information within a quantum system with many continuous degrees of freedom. The practical implementation of this idea requires complete control over all of the 2n independent amplitudes of a many-particle wave function, where n>1000. The principles of quantum computing are discussed from the practical point of view, with the conclusion that a working device cannot be built in the foreseeable future.
