Asymptotically optimal quantum channel reversal for qudit ensembles and multimode Gaussian states
We investigate the problem of optimally reversing the action of an arbitrary quantum channel C which acts independently on each component of an ensemble of n identically prepared d -dimensional quantum systems. In the limit of large ensembles, we construct the optimal reversing channel R ^☆ _n which...
