Quantum communication in general helps deter potential eavesdropping in the course of transmission of bits to enable secure communication between two or more parties. In this paper, we propose a novel quasi-deterministic secure quantum communication scheme using non-maximally entangled states. The proposed scheme follows a simple procedure, and cases where the entanglement required can be significantly reduced to carry out the protocol successfully are discussed. Long sequences or the whole sequence of data can be sent after error checking for a potential eavesdropper. The maximum qubit efficiency of the proposed protocol is found to be 33.333%.

使用非最大纠缠态的准确定性安全量子通信

量子通信通常有助于阻止比特传输过程中的潜在窃听，以实现两方或多方之间的安全通信。在本文中，我们提出了一种使用非最大纠缠态的新型准确定性安全量子通信方案。所提出的方案遵循一个简单的程序，并且讨论了可以显着减少以成功执行协议所需的纠缠的情况。在对潜在窃听者进行错误检查后，可以发送长序列或整个数据序列。发现所提出协议的最大量子比特效率为 33.333%。
