Research on Spin Wave interference device for Quantum computation application

磁振子是自旋波（SWs）的量子，是后CMOS技术最有前途的候选者。与CMOS不同，该技术不受焦耳加热的影响，可以对振幅和相位的数据进行编码。然而，由于缺乏高效节能的水处理控制机制，影响了其应用。因此，我一直在寻找一种新的节能SWs控制机制。我提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。首次在Au/PEDOT:PSS/Pt/YIG多层材料中使用有机离子聚合物（PEDOT:PSS），提出了一种新型的e场控制微结构sw器件。在调查过程中，我也澄清了一些有趣的静态物理（AIP Advances, 10,015015 (2020), IEEE Trans）。磁学学报，58(2),4300706(2022)，自然科学rep 12, 11105(2022))和dynamic（苹果公司）。体育。列托人。[j] .自然科学学报，2017,33(2):481 - 481。此外，作者首次证明了在微结构铁磁YIG横条中，使用来自两种不同SW模式（静磁表面SW和后体积静磁SW）的不对称波载体对磁振子干涉的系统控制。使用这个系统，我通过电刺激来调整波矢量，以证明干涉图中的相位可重构性。我们证明了这种可调谐干扰可以分别使用对称和非对称干扰来实现在XNOR和XOR模式之间工作的可重构逻辑门(Sci。众议员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)).
