Quantum Computing Using Dissipation to Remain in a Decoherence-Free Subspace

Abstract

We propose a new approach to the implementation of quantum gates in which decoherence during the gate operations is strongly reduced. This is achieved by making use of an environment induced quantum Zeno effect that confines the dynamics effectively to a decoherence-free subspace.
