Abstract

In this paper, a novel semiquantum key distribution (SQKD) protocol is proposed using Bell states, where quantum Alice can share secret bits with semiquantum Bob via a quantum channel. Semiquantum Bob is required to measure particles with the basis (i.e. ), produce fresh particles within the basis and send particles via a quantum channel. Security analysis turns out that this protocol is immune to various attacks launched by the outside eavesdropper. Compared with present SQKD protocols using Bell states without a third party (Sun et al 2011 arXiv:1106.2910v3; Wang et al 2011 Chin. Phys. Lett.28 100301; Wu et al 2022 Front. Phys. 10 1029262), on the one hand, this protocol has the highest qubit efficiency; and, on the other hand, the reflecting operations of the semiquantum user in this protocol contribute to the generation of final shared keys.

具有贝尔态的新型半量子密钥分发协议

本文提出了一种使用贝尔态的新型半量子密钥分发（SQKD）协议，量子爱丽丝可以通过量子信道与半量子鲍勃共享秘密比特。半量子鲍勃需要用基础（即）测量粒子，在基础内产生新粒子，并通过量子信道发送粒子。安全分析表明，该协议可以抵御外部窃听者发起的各种攻击。与目前使用贝尔态而没有第三方的 SQKD 协议相比（孙等人 2011 arXiv:1106.2910v3; 王等人 2011 Chin.Lett.28 100301；Wu 等人 2022 Front.10 1029262），一方面，该协议具有最高的量子比特效率；另一方面，该协议中半量子用户的反射操作有助于生成最终的共享密钥。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
