Entanglement Swapping for Displaced Two-Mode Squeezed States
Entanglement Swapping for Displaced Two-Mode Squeezed States
摘要
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 originM 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.
