Abstract

In this paper, we study Susskind–Glogower phase distribution of entangled state in the framework of interactions involving two modes of interacting Fock space which in its turn provides an interesting insigth into the structure of entangled state.

SQUEEZING ENHANCED THREE-MODE ENTANGLED STATE

Liyun Hu, Hong-Yi Fan

By virtue of the technique of integration within an ordered product of operators (Fan et al., Ann. Phys.321 (2006) 480) we construct a kind of three-mode entangled squeezed state in the Fock space, which exhibits stronger squeezing in one quadrature than that of the usual two-mode squeezed vacuum state.

Phase Properties of Two-Mode Squeezing-Rotating Entangled Representation

Yuan Hong-Chun, Heng-Mei Li, Qi Kai-Guo

By virtue of the squeezing-rotating entangled representation, we mainly establish the new two-mode phase operator and phase angle operator, which is a general form including the foregoing formalist in two-mode Fock space. In addition, the corresponding phase distribution function is given in the entangled representation. In terms of this definition, we also analyze the phase behavior of some simple two-mode states such as squeezing-rotating coherent state, squeezing-rotating vacuum state, and so on. It is found that the results exactly agree with the foregoing phase theory.

EVALUATOIN OF ENTANGLEMENT OF ENTANGLED COHERENTSTATES WITH SYMMETRY IN PHASE SPACE

Gong Ren-shan

This paper has studied two kinds of entangled coherent states with symmetry in phase space.It is proved that their entanglements have relations with the strength or relative phase factors of two two-mode coherent states.Some formulas for evaluating entanglements of these entangled coherent states are derived.Finally,some possible way for improving their entanglements are proposed.
