Research on Spin Wave interference device for Quantum computation application

磁振子是自旋波的量子，是后CMOS工艺中最有前途的候选者。与CMOS不同，该技术不受焦耳热的影响，并且可以在幅度和相位上对数据进行编码。然而，由于缺乏节能控制机制，其应用一直受到影响。因此，我一直在寻找一种新的节能SW控制机制。我想出了一个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。本文首次提出了一种在Au/PEDOT：PSS/Pt/YIG多层膜中引入有机离子聚合物（PEDOT：PSS）的电场控制微结构慢波器件。在研究过程中，我还澄清了一些有趣的静态物理学（AIP Advances，10，015015（2020），IEEE Trans. on Magnetics，58（2），4300706（2022），Sci. 12，11105（2022））和动态（Appl. Phy.信件：此外，我第一次展示了在微结构铁磁YIG交叉杆中使用来自两种不同SW模式（静磁表面SW和后向体积静磁SW）的非对称波矢量对磁振子干扰的系统控制。使用这个系统，我调谐的波矢量的电刺激，以证明相位重构的干涉图案。我们证明，这种可调干扰可以用来实现可重构逻辑门之间的XNOR和XOR模式操作，通过使用对称和非对称干扰，分别（科学。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)).
