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.
