摘要
A 1 -> 2 telecloning solution for an arbitrary three-particle entangled W state is proposed in which two four-particle entangled states are used as quantum channels. It is proposed that the three-particle W state can be telecloned based on the quantum teleportation and the local copying of entanglement, and the fidelity of each clone depends on the input state. This scheme can be generalized into the case of 1 -> N (N > 2) telecloning of an arbitrary three-particle W state. Furthermore, another scheme for 1 -> N (Na parts per thousand yen2) telecloning of an arbitrary n-particle (na parts per thousand yen4) W state is proposed, the multi-bit controlled-NOT (CNOT) gates and additional particles are needed in this case.
