Refocusing schemes for holonomic quantum computation in the presence of dissipation
Li-Xiang Cen, Paolo Zanardi · Physical Review A · 2004
The effects of dissipation on a holonomic quantum computation scheme are analyzed within the quantum-jump approach. We extend to the non-Abelian case the refocusing strategies formerly introduced for (Abelian) geometric computation. We show how double loop symmetrization schemes allow one to get rid of the unwanted influence of dissipation in the no-jump trajectory.
