摘要：
We show how the entangled state representation (eta\ (H. Fan, J.R. Klauder, Phys. Rev. A 49 (1994) 704, eta is a continuous variable), which entangles two particles in the sense of relative coordinate and total momentum initiated by Einstein, Podolsky and Rosen, can be directly applied to quantum teleportation to make detailed analysis and calculation, Our derivation is concise due to using the neat expression of the two-mode squeezing operator in the entangled state representation.
