中文摘要:
我们在场为改进那的来源能力的稠密的编码计划最近由张等介绍了的完全的多重圆量。接收装置为在每个回合存储四本地单一的操作诉诸二 qubits。量纠纷提供一些新奇方法播送并且处理量信息,例如它介绍的量计算和量通讯一个量系统的非地区。就算他们是差距很大的,由量系统组成的二个分系统不能被认为独立。二个分系统上的任何测量不能独立关于量系统给所有信息。量纠纷广泛地在量计算和量通讯被使用了,例如量稠密的编码,量钥匙分发,量安全直接通讯,并且量秘密分享。
英文摘要:
We present a complete multiple round quantum dense coding scheme for improving the source capacity of that introduced recently by Zhang et al. The receiver resorts to two qubits for storing the four local unitary operations in each round.
