摘要: 针对当前同时密集编码中接收方数量受限问题, 通过引入n 比特量子傅里叶变换, 提出了具有多个接收方 的非受控和受控同时密集编码协议。在非受控多方同时密集编码协议中,发送方在待传粒子上执行编码以及加锁操 作, 接收方只有联合执行解锁操作, 才能同时获得最终的编码信息; 在受控多方同时密集编码协议中, 只有全体接收 者在控制者的允许下通过协作才能完成信息的传输。通过对内部和外部攻击进行了分析, 证实了同时密集编码协议 的安全性。此外, 所提出的方案中只使用Bell 基测量, 在实验条件下容易实现。

Abstract: Aiming at the limited number of receivers in current simultaneous dense coding, an uncontrolled or controlled simultaneous dense coding protocol with multiple receivers is proposed by introducing n-bit quantum Fourier transform. In the uncontrolled multi-party simultaneous dense coding protocol, after the sender performs encoding and locking operations on the particles to be transmitted, only the receivers perform unlocking operations jointly, can they obtain the final encoding information at the same time. While in the controlled multi-party simultaneous dense coding protocol, only all receivers cooperate with the permission of the controller, can the transmission of information be completed. The security of the proposed protocol is verified by analyzing internal and external attacks. Besides, only Bell measurement is used in the proposed scheme, which is easy to implement under experimental conditions.

Key words: quantum communication, simultaneous dense coding, Fourier transform, controlled simultaneous dense coding
