Quantum Cloning of Steering
文献摘要：
Quantum steering in a global state allows an observer to remotely steer a subsystem into different ensembles by performing different local measurements on the other part.We show that,in general,this property cannot be perfectly cloned by any joint operation between a steered subsystem and a third system.Perfect cloning is viable if and only if the initial state is of zero discord.We also investigate the process of cloning the steered qubit of a Bell state using a universal cloning machine.Einstein-Podolsky-Rosen(EPR)steering,which is a type of quantum correlation existing in the states without a local-hidden-state model,is observed in the two copy subsystems.This contradicts the conclusion of no-cloning of quantum steering(EPR steering)[C.Y.Chiu et al.,npj Quantum Inf.2,16020(2016)]based on a mutual information criterion for EPR steering.
