该文提出了一种以团簇态为量子信道的受控超密编码方案.研究结果表明:通过调节测量角的取值,监控者可以控制发送者和接收者之间的信息发送量,并且可以控制发送者和接收者之间量子信道的纠缠度.
A controlled dense coding scheme is investigated via cluster state. It is shown that the amount of classical information and the entanglement between the sender and the receiver are controlled by the controllers through adjustments of the local measurement angles.
