Optimal cloning for finite distributions of coherent states
P. T. Cochrane, T. C. Ralph, A. Dolinska
abstract: We derive optimal cloning limits for finite Gaussian distributions of
coherent states, and describe techniques for achieving them. We discuss the
relation of these limits to state estimation and the no-cloning limit in
teleportation. A qualitatively different cloning limit is derived for a
single-quadrature Gaussian quantum cloner.
