✦ Synopsis

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-pulse techniques. We discuss the dynamics of resonant pulse implementations of quantum logic gates in Ising spin systems. We also discuss the influence of non-resonant excitations. We calculate the range of parameters where undesirable non-resonant effects can be minimized. Finally, we describe the "2Ο€k-method" which avoids the detrimental deflection of non-resonant qubits.

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 p
