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.

我们研究了通过海森堡相互作用耦合并受两个独立耗散环境影响的两个通道量子位的量子隐形传态和贝尔非局域性。与两个非耦合量子比特的情况相比，表明相互作用哈密顿量有利于提高隐形传态保真度和贝尔非局域性，而且值得注意的是，它甚至可以从初始产品状态创建非经典隐形传态保真度和贝尔非局域性。此外，相互作用哈密顿量保证了稳态非经典隐形传态保真度的产生，它与初始状态无关，因此可以将任何状态作为初始通道状态。
