论文摘要
对于实现变革性量子信息技术的启用可扩展性和节能控制自旋缺陷是可取的。利用电压控制的磁各向异性,我们报告了通过近端谐振磁性隧道连接点(MTJ)产生的空间限制的磁性流量场对氮相处(NV)中心的相干操纵。值得注意的是,NV中心与MTJ之间的相干耦合可以通过直流偏置电压系统控制,从而可以在呈现的混合系统中可显着可调。与当前的最新技术相比,所展示的基于NV的量子操作平台在可伸缩性,设备兼容性和能源效率方面具有显着优势,进一步扩大了NV中心在广泛的量子计算,传感和通信应用中的作用。
Enabling scalable and energy-efficient control of spin defects in solid-state media is desirable for realizing transformative quantum information technologies. Exploiting voltage-controlled magnetic anisotropy, we report coherent manipulation of nitrogen-vacancy (NV) centers by the spatially confined magnetic stray fields produced by a proximate resonant magnetic tunnel junction (MTJ). Remarkably, the coherent coupling between NV centers and the MTJ can be systematically controlled by a DC bias voltage, allowing for appreciable electrical tunability in the presented hybrid system. In comparison with current state-of-the-art techniques, the demonstrated NV-based quantum operational platform exhibits significant advantages in scalability, device compatibility, and energy-efficiency, further expanding the role of NV centers in a broad range of quantum computing, sensing, and communications applications.
