Abstract: | Based on EPR’s idea of quantum entanglement, new parameterized coherent-entangled states |α,p〉 μ,ν are introduced in two-mode Fock space, which can be implemented by using a beam splitter. Possible superpositions of |α,p〉 μ,ν result in some new entangled states. The asymmetric ket-bra integration from |α,p〉 μ,ν leads to a new one- and two-mode combinatorial squeezing operator with stronger squeezing, which clearly shows the intrinsic relationship between squeezing mechanism and quantum entanglement. |
