New bipartite coherent-entangled state in two-mode Fock space and its applications

► We have proposed a new bipartite CES in two-mode Fock space. ► In the process of deriving the new bipartite CES, we use the advanced IWOP technique. ► Based on the newly introduced CES │α,x>, we obtain some new quantum entangled states and some one- and two-mode combinatorial squeezing operators. This reveals the intrinsic relation between entanglement and squeezing.
