BIPARTITE SQUEEZING OPERATOR FROM COHERENT ENTANGLED STATE GENERATED BY ASYMMETRIC BEAMSPLITTER
Qingqiang Kuang, Liyun Hu · Modern Physics Letters B · 2011
With use of the newly proposed bipartite coherent entangled state (generated by asymmetric beamsplitter) and by projecting both the classical symplectic transform and the classical dilation one in phase space onto quantum mechanical Hilbert space, we construct a six-parameter squeezing operator, which has its own squeezing property, in a natural way. The derivation is implemented on the basis of the technique of integration within an ordered product of operators and the completeness of the bipartite coherent entangled state.
