Conditions for the local manipulation of Gaussian states

Quantum Physics 2009-11-07 v2

Abstract

We present a general necessary and sufficient criterion for the possibility of a state transformation from one mixed Gaussian state to another of a bi-partite continuous-variable system with two modes. The class of operations that will be considered is the set of local Gaussian completely positive trace-preserving maps.
