利用纠缠相干态实现量子概率隐形传态

Quantum probabilistic teleportation via entangled coherent states

Shang-Bin Li Jing-Bo Xu

摘要:

利用形成纠缠研究了真空环境中纠缠相干态的纠缠,提出了一种利用纠缠相干态概率传送相干叠加态的方案,其中Alice发送的经典信息量被限制在1比特以内.考虑了光子耗散引起的退相干的影响。结果表明,在某些情况下,消相干可以提高概率隐形传态的平均保真度。

英文摘要:

We study the entanglement of entangled coherent states in vacuum environment by employing the entanglement of formation and propose a scheme to probabilistically teleport a coherent superposition state via entangled coherent states, in which the amount of classical information sent by Alice is restricted to one bit. The influence of decoherence due to photon absorpation is considered. It is shown that decoherence can improve the mean fidelity of probabilistic teleportation in some situations.
