摘要

We investigate quantum teleportation and Bell nonlocality for two channel qubits coupled via the Heisenberg interaction and subject to two independent dissipative environments.Compared with the case of two uncoupled qubits,it is shown that the interaction Hamiltonian is beneficial for enhancing the teleportation fidelity and Bell nonlocality,and remarkably,it can also be used to create nonclassical teleportation fidelity and Bell nonlocality even from the initial product states.Moreover,the interaction Hamiltonian guarantees the generation of steady-state nonclassical teleportation fidelity,which is independent of the initial state and therefore one can take any state as the initial channel state.
