Calculation of entanglement for continious variable states
Huai-XIn Lu, Zeng-Bing Chen, Jian-Wei Pan +1
In this paper, we present a general formula for obtaining the reduced density opeator for any biparticle pure entangled state. Using this formula, we derive, in a compact form, the…

Linear Optics Quantum Communication over Long Distances
Zeng-Bing Chen, Huai-Xin Lu, Yong-De Zhang
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…
