长距离线性光学量子通信

Linear Optics Quantum Communication over Long Distances

Zeng-Bing Chen, Huai-Xin Lu, Yong-De Zhang

摘要:

我们提出了一个可行的方案,通过只需要单光子(SP)源,简单的线性光学元件和SP量子非破坏性测量隐形传态的任意偏振态或纠缠的光子。一个未知的SP偏振态可以忠实地传送到一个复制的偏振态或纠缠态。我们的方案可以用一种简单的方式实现长距离量子通信。该方案是在现有技术的范围内,并显着简化了现实的实现远距离高保真量子通信与光子量子比特。

英文摘要:

We propose a feasible scheme for teleporting an arbitrary polarization state or entanglement of photons by requiring only single-photon (SP) sources, simple linear optical elements and SP quantum non-demolition measurements. An unknown SP polarization state can be faithfully teleported either to a duplicate polarization state or to an entangled state. Our proposal can be used to implement long-distance quantum communication in a simple way. The scheme is within the reach of current technology and significantly simplifies the realistc implementation of long-distance high-fidelity quantum communication with photon qubits.
