摘要
建议一个使用非最大纠缠态通道远程执行部分未知量子操作的协议,并且显示,当采用非最大纠缠粒子对作为量子通道时,由引进一个集中的幺正变换使得部分未知的量子操作能够被概率地远程执行.讨论了在这种情况下,部分未知的量子操作远程执行的成功概率以及所需要的资源.
A protocol for remote implementation of partially unknown quantum operation using a nonmaximally entangled channel was proposed and it was shown that when nonmaximally entangled pairs were taken as quantum channels, the partially unknown quantum operation could be remotely implemented probabilistically by introducing a collective unitary transformation. The required resources for remote implementation of the partially unknown quantum operation in this case were discussed.
