Optimal cloning of coherent states by linear optics

Quantum Physics 2009-11-13 v2

Abstract

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.
