Deciding separability with a fixed error

Quantum Physics 2009-11-10 v1

Abstract

We give a short proof of the cross norm characterization of separability due to O. Rudolph and show how its computation, for a fixed chosen error, can be reduced to a linear programming problem whose dimension grows polynomially with the inverse of the error.
