Abstract

We propose a feasible method of coherent-state information concentration and purification utilizing quantum memory. The method allows us to optimally concentrate and purify information carried by many noisy copies of an unknown coherent state (randomly distributed in time) to a single copy. Thus non-classical resources and operations can be saved, if we compare information processing with many noisy copies and a single copy with concentrated and purified information.
