Quantum computers and quantum computations

Institute of Physics and Technology, Russian Academy of Sciences, Nakhimovskii prosp. 34, Moscow, 117218, Russian Federation

This review outlines the principles of operation of quantum computers and their elements. The theory of ideal computers that do not interact with the environment and are immune to quantum decohering processes is presented. Decohering processes in quantum computers are investigated. The review considers methods for correcting quantum computing errors arising from the decoherence of the state of the quantum computer, as well as possible methods for the suppression of the decohering processes. A brief enumeration of proposed quantum computer realizations concludes the review.
