摘要
Based on the neat<η|representation of two-mode squeezing operator which entangles signal-mode and idle-mode,where<η|is the common eigenvector of two particles'relative position 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.
