A new quantum teleportation protocal
量子隐形传态的新方案

A new quantum teleportation protocol is addressed in this article. By performing the joint measurement of number-phase on a pair of independent two-mode squeezed vacuum states (1- 2 and 3- 4 systems), whose squeezed parameters are the same, the entangled states of the other two bodies (1- 4 systems) as the entangled resource are prepared. Thus the quantum teleportation is successfully realized.
