Mixed Squeezing for a Pair of Two-Mode Squeezed States
Fan Hong-Yi, Nai-Le Liu · Chinese Physics Letters · 2001
Based on the neat ⟨η| representation of the two-mode squeezing operator which entangles signal-mode and idle-mode, 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.
