Quantum Cloning of Steering

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