摘要

提出了一种在新型线性光网络中构建连续变奇偶相干纠缠信道的可行方案。讨论了期望纠缠信道的纠缠度和产生最大纠缠的成功概率。结果表明,当两个平行分束器相同时,该方案产生的纠缠信道的纠缠度仅与辅助分束器有关,并且对于给定的辅助分束器(如对称平衡分束器),随着两个平行分束器反射系数的增加和初始输入相干参数的减小,产生最大纠缠信道的成功概率提高。

Scheme for Remote Construction of Continuous Variable Entangled Channel via Beam Splitters
A feasible scheme for construction of continuous variable odd-even coherent entangled channel is proposed in a novel linear optical network. The degree of entanglement of the desired entangled channel and success probability for generating maximal entanglement are discussed. It is showed that the degree of entanglement of the entangled channel generated in our scheme is only related with the assisted beam splitter when the two parallel ones are identical, and the success probability of generating maximally entangled channel improves with the increasing of the reflection coefficients of two parallel beam splitters and decreasing of the initial input coherent parameters for a given assisted beam splitter, such as a symmetrically balanced one.
