摘要

Based on the neat 〈η｜ representation of the two-mode squeezing operator which entangles signal-mode and idlemode, where〈η｜ is the common eigenvector of the relative position of two particles and the total momentum exhibiting a maximal entanglement between the two modes, we study some kind of squeezing mixing 1-3 modes and 2-4 modes for a pair of two-mode (1－2 modes and 3－4 modes) squeezed states. The explicit form of such mixed squeezed states is derived and the new entanglement is analysed.
