Research on Spin Wave interference device for Quantum computation application

作为自旋波量子的磁振子是最有希望成为后CMOS技术的候选者。与cmos不同的是，这种技术不受焦耳加热的影响，可以对数据进行幅度和相位编码。然而，由于缺乏有效的节能控制机制，其应用受到了阻碍。因此，我一直在寻找一种新型的节能的SWS控制机制。我想出了一种全新的方法来控制磁振子，基于电场诱导的动态氧化还原反应。首次提出了一种在Au/PEDOT：PSS/铂/YIG多层膜中使用有机离子聚合物(PEDOT：PSS)的新型电场控制微结构表面波散射器件。在调查过程中，我还澄清了一些关于静态的有趣物理(AIP Advance，10,015015(2020年)，IEEE Transans。《磁学》，58(2)，4300706(2022年)，《科学》。代表12,11105(2022年))和动态(应用PHY。此外，我还首次展示了在微结构铁磁YIG横杆中使用来自两种不同的短波模式(静磁表面短波和后向体静磁短波)的非对称波矢对磁非干扰的系统控制。利用该系统，通过电刺激对波矢进行调谐，演示了干涉图中的相位可重构性。我们证明了这种可调干涉可以分别使用对称干涉和非对称干涉来实现在XNOR和XOR模式之间工作的可重构逻辑门(Sci。代表13,4872(2023))。

Magnon, which is the quanta of spin waves (SWs) is the most promising candidate for post CMOS technology. Unlike CMOS, this technology is immune to Joule heating and can encode data in both amplitude and phase. However, its application has been undermined due to lack of energy efficient control mechanism of the SWs. Therefore, I have searched for a novel energy efficient SWs control mechanism. I came up with a completely new approach to control the magnon, based on the electric field induced dynamic redox reaction. I, for the first time, proposed a new type of E-filed controlled micro structured SWs device using an organic ionic polymer (PEDOT:PSS) in the Au/PEDOT:PSS/Pt/YIG multilayer. During the investigation process I also have clarified few interesting physics for static (AIP Advances, 10, 015015 (2020), IEEE Trans. on Magnetics, 58(2), 4300706 (2022), Sci. Rep. 12, 11105 (2022)) and dynamic (Appl. Phy. Lett., 117, 152403 (2020)) control of SWs.Furthermore, I for the first time demonstrated systematic control of magnon interference using asymmetric wavevectors from two different SW modes (magnetostatic surface SWs and backward volume magnetostatic SWs) in a microstructured ferromagnetic YIG crossbar. Using this system, I tuned the wave vectors by electrical stimulus to demonstrate phase reconfigurability in the interference pattern. We prove that such a tunable interference can be used to implement reconfigurable logic gates operating between the XNOR and XOR modes by using symmetric and asymmetric interference, respectively (Sci. Rep. 13, 4872 (2023)).
