Optimal discrimination of quantum states on a two-dimensional Hilbert space by local operations and classical communication

Quantum Physics 2018-01-12 v1

Abstract

We study the discrimination of multipartite quantum states by local operations and classical communication. We derive that any optimal discrimination of quantum states spanning a two-dimensional Hilbert space in which each party's space is finite dimensional is possible by local operations and one-way classical communication, regardless of the optimality criterion used and how entangled the states are.
