Optimal cloning of coherent states by linear optics
Olivares, S, Paris, M G A, Ulrik L. Andersen · CERN Document Server (European Organization for Nuclear Research) · 2006
We describe an optical scheme for optimal Gaussian n to m cloning of coherent states. The scheme, which generalizes a recently demonstrated scheme for 1 to 2 cloning, involves only linear optical components and homodyne detection.
