摘要:

利用纠缠的相对熵研究了相位阻尼信道中猫对态的纠缠。结果表明,在相位阻尼通道中,猫对态总是可分离的。此外,我们还利用光子数和和相位差的联合测量分析了对猫态隐形传态的保真度。

英文摘要:

The entanglement of pair cat states in the phase damping channel is studied by employing the relative entropy of entanglement. It is shown that the pair cat states can always be distillable in the phase damping channel. Furthermore, we analyze the fidelity of teleportation for the pair cat states by using joint measurements of the photon-number sum and phase difference.
