Holonomic Quantum Computation in Decoherence-Free Subspaces
Lian-Ao Wu, Paolo Zanardi, Daniel A. Lidar · Physical Review Letters · 2005
We show how to realize, by means of non-Abelian quantum holonomies, a set of universal quantum gates acting on decoherence-free subspaces and subsystems. In this manner we bring together the quantum coherence stabilization virtues of decoherence-free subspaces and the fault tolerance of all-geometric holonomic control. We discuss the implementation of this scheme in the context of quantum information processing using trapped ions and quantum dots.
