多粒子量子态的超空间克隆

Telecloning of unknown N-dimensional quantum state

将多粒子量子态的最优克隆和超空间转移结合起来,给出了多粒子态量子超空间克隆的方案,通过对该方案与先克隆再超空间转移方案之间所耗的纠缠资源的比较分析,发现该方案具有消耗纠缠资源少的优点。

An N-dimensional quantum telecloning process combining quantum teleportation and optimal quantum cloning is presented.The scheme requires less entanglement between the two sides,representing a much more efficient than the approach where Alice first clones her particle and then teleports these states.
