摘要：

We propose a protocol to implement the nonlocal Bell-state measurement,which is nearly determinate with the help of weak cross-Kerr nonlinearities and quantum non-destructive photon number resolving detection.Based on the nonlocal Bell-state measurement,we implement the quantum information transfer from one place to another.The process is different from conventional teleportation but can be regarded as a novel form of teleportation without entangled channel and classic communication.
