给出远程两态1→M概率量子克隆的方案和成功概率。相比标准的量子隐形传态传输1个粒子,整个系统需要消耗两个粒子而言,方案极大地节省了纠缠粒子数。本方案可以作为量子密码术中著名的B92方案的延拓。

We investigate a protocol of the telecloning of 1→M probabilistic quantum cloning of two states,and derive the success probability.Compared with the standard teleportation that is required to use up two particles for transmitting one particle,our protocol can greatly save the number of the sources of entangled states.The protocol can be regarded as a development of the well-known B92 protocol in quantum cryptography.
