No-cloning theorem in thermofield dynamics [PDF]
Thiago PrudencioWe 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.View original: http://arxiv.org/abs/1104.3926
