2020 computing: Champing at the bits.

The article provides information on the would-be practical quantum computers intended to be used for quantum computing. Despite some hurdles, Andrew Steane of the quantum-computing group at the University of Oxford in Great Britain declared that useful computer is realistic by 2020. Likewise, David Deutsch agreed the declaration of Steane stressing that he is optimistic that a practical quantum computer will be achieved within the next decade in relation to the recent theoretical advances.
