Entanglement Swapping for Displaced Two-Mode Squeezed States

Fan Hong‐Yi, Hui Wang

Published Oct 15, 2001• 2 citations
Publisher

Abstract

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.

Squeeze-swapping by Bell measurement studied in terms of the entangled state representation

Xuechao Li, Chuanmei Xie, Fan Hong‐Yi

By virtue of the entangled state representation (Hong-Yi Fan and J R Klauder 1994 Phys. Rev. A 49 704) and the two-mode squeezing operator's natural representation (Hong-Yi Fan and Yue Fan 1996 Phys. Rev. A 54 958) we propose the squeeze-swapping mechanism which can generate quantum entanglement and new squeezed states of continuum variables.

Mixed Squeezing for a Pair of Two-Mode Squeezed States

Fan Hong-Yi, Nai-Le Liu

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.
