Entanglement Swapping for Displaced Two-Mode Squeezed States
Fan Hong‐Yi, Hui Wang · Communications in Theoretical Physics · 2001
We discuss the entanglement swapping of two pairs of displaced two-mode squeezed states and find that the squeezing parameter of the outcoming squeezed state is less than that of the original squeezed states. The calculation is greatly simplified by virtue of the natural expression of the two-mode squeezing operator in EPR eigenstate representation. A protocol for such entanglement swapping is proposed.
