| Abstract: | In this paper,a scheme was proposed which can teleport N-qubit quantum state by means of nEinstein-Podolsky-Rosen(EPR)pairs.In the proposed scheme,entangled EPR state is used as quantum channel between a sender and a receiver,the teleportaion of N-qubit unknown quantum state can be realized by means of N joint measurement and relevant unitary transformation.This scheme can teleport more information than using singlet particle quantum state. |
