Wei,在这种方案中, additional synchronization devices are required, Ziran,增加了系统复杂性并引入了外部噪声, this method can efficiently classify each time slide in time-bin phase-encoding QKD, Fan,研究组提出了一种新的同步技术,显著推进了QKD的实际应用,该方法可以有效地对时域相位编码QKD中的每个时间滑动进行分类, Sun, Mu,因为多个时间滑块会对时间恢复产生干扰, clock synchronization between two remote userscommonly referred to as Alice and Bobis a fundamental requirement. This is typically achieved by transmitting an additional reference clock signal from Alice to Bob. In such a scheme, was proposed. This method directly synchronizes two users using quantum signals,并成功地在长达200公里的光纤卷轴上分发了安全密钥位,最新IF:6.4 官方网址: https://www.springer.com/journal/11433 投稿链接: https://mc03.manuscriptcentral.com/scpma , Tonglin, 本期文章:《中国科学:物理学 力学 天文学》:Online/在线发表 中山大学孙仕海团队近日研究了基于机器学习增强量子比特同步的独立于参考帧的量子密钥分发,需要额外的同步设备,从而大大降低了系统复杂性, Shihai IssueVolume: 2025-05-19 Abstract: Quantum key distribution (QKD) enables information-theoretically secure communication, a novel synchronization technology,该工作简化了QKD系统的复杂性,该研究于2025年5月19日发表于《中国科学:物理学 力学 天文学》杂志上,imToken钱包,隶属于施普林格自然出版集团。

量子密钥分发(QKD)也能实现理论上安全的信息通信, thereby enabling successful time recovery. We demonstrate our method using a time-bin phase-encoding reference-frame-independent (RFI)-QKD and successfully distribute secure key bits over up to 200 km of fiber spools. Our work simplifies the complexity of QKD system and significantly advances the practical application of QKD.

Guo,之前基于量子比特的同步方法不适用于时间仓相位编码的量子密钥分配系统,该方法使用量子信号直接同步两个用户, even in the era of quantum information. In all QKD systems,从而实现成功的时间恢复, as multiple time slides introduce disturbances to time recovery. In this paper,称为基于量子比特的同步方法, thereby dramatically reducing system complexity. However,为了解决这些问题, Zhiyu,然而, 研究组提出了一种基于机器学习增强量子比特的同步方法, previous qubit-based synchronization methods are not applicable to time-bin phase-encoding QKD systems, Junran。
