No-cloning theorem in thermofield dynamics

Quantum Physics 2015-03-19 v5 Mathematical Physics math.MP

Abstract

We discuss the relation between the no-cloning theorem from quantum information and the doubling procedure used in the formalism of thermofield dynamics (TFD). We also discuss how to apply the no-cloning theorem in the context of thermofield states defined in TFD. Consequences associated to mixed states, von Neumann entropy and thermofield vacuum are also addressed.
