Bath-Optimized Minimal-Energy Protection of Quantum Operations from Decoherence
Jens Christian Clausen, Guy Bensky, Gershon Kurizki · Physical Review Letters · 2010
We put forward a general strategy for dynamic control that ensures bath-optimized fidelity of a desired multidimensional quantum operation in the presence of non-Markovian baths and noises with stationary autocorrelations. It benefits from the vast freedom of arbitrary, not just pulsed, time-dependent control. This allows the dramatic reduction of the invested energy and the corresponding error compared to pulsed control.
