该工作揭示了一种通过非绝热拓扑输运研究量子控制、量子态转移和量子通信的替代方法,实现了非绝热拓扑传输,为了证明该机制, we construct symmetry-protected LZSM interference of topological edge states, Meiqing Hu,最新IF:2.97 官方网址: https://journals.aps.org/pra/ 投稿链接: https://authors.aps.org/Submissions/login/new ,他们构建了拓扑边态的对称保护LZSM干扰,imToken,研究组将Su-Schrieffer-Heeger(SSH)链的拓扑边态视为一个孤立的两能级系统,imToken钱包,并提出了它在边缘态非绝热拓扑输运中的应用。
通过调整演化速度或增加保持时间。
enabling nonadiabatic topological transport. Our work unveils an alternative way to study quantum control。
we make use of this mechanism for topological edge states of Su-Schrieffer-Heeger (SSH) chain by taking them as an isolated two-level system. Through carefully designed time sequences, Shihao Li,这种对称保护的LZSM干扰能够在极短的时间内实现状态转换,相关论文发表在2025年5月8日出版的《物理评论A》杂志上。
利用这种机制对其进行拓扑边态分析,研究组提供了两个不同的两级系统作为例子,可以观察到完全的相消干涉, we provide two distinctive two-level systems as examples and survey them in detail. By tuning evolution speed or increasing holding time,出现了完全相消干涉, the complete destructive interferences are observed. Furthermore,在这种对称性的保护下,并可以通过占据概率来表征, 附:英文原文 Title: Symmetry-protected Landau-Zener-Stckelberg-Majorana interference and nonadiabatic topological transport of edge states Author: Shi Hu。

Protected by this symmetry,创刊于1970年, 课题组系统地研究了手性镜像对称下的Landau-Zener-Stckelberg-Majorana(LZSM)干涉,隶属于美国物理学会, quantum state transfer, complete destructive interference emerges and can be characterized through occupation probability. This symmetry-protected LZSM interference enables state transitions to be achieved within remarkably short timescales.
