✦ Synopsis

A practically useful quantum computer would be a large quantum network ready to support a universal set of unitary transformations. By these transformations one would generate quantum states at will out of the zero-entropy ground-state, the state of initialization. To what extent this will ever be possible is not known yet. Here we propose to consider such computers as a special class of quantum machines aimed at the exploitation and manipulation of nonequilibrium states. Their control limits should thus apply also to quantum information processing.

We discuss the dynamical issues of quantum computation. We demonstrate that fast wave function oscillations can affect the performance of Shor's quantum algorithm by destroying the required quantum interference. We also show that this destructive effect can be routinely avoided by using resonant-pul
