A new bipartite coherent–entangled state generated by an asymmetric beamsplitter and its applications
Liyun Hu, Hong-Yi Fan · Journal of Physics B Atomic Molecular and Optical Physics · 2007
A new kind of bipartite coherent–entangled state (CES) is introduced which exhibits both coherent state and entangled state properties. A protocol of generating such a CES is proposed using an asymmetric beamsplitter. It is shown that the bipartite EPR entangled state can be a superposition of the CESs. Applications of CESs in quantum optics are also presented.
