论文摘要
量子工程中正在进行的努力最近着重于将镁化学纳入新功能的混合量子体系结构中。尽管钻石中的氮呈（NV）中心已经证明了杂化镁量子自旋系统，但它们在技术上有希望的碳化硅（SIC）平台上仍然难以捉摸，这主要是由于难以在Magnonic System和Spiners和Spiners之间找到共振重叠的困难。在这里，我们通过在磁性涡流中利用非线性镁散射过程来验证这一挑战，以访问与硅胶合频率重叠的木片模式（$ \ textrm {v} _ {\ mathrm {si}} $）SIC中的旋转过渡。我们的结果提供了一种开发混合系统的途径，该途径将受益于将镁的丰富非线性动力学与SIC具有可扩展量子技术的优势性能。
Ongoing efforts in quantum engineering have recently focused on integrating magnonics into hybrid quantum architectures for novel functionalities. While hybrid magnon-quantum spin systems have been demonstrated with nitrogen-vacancy (NV) centers in diamond, they have remained elusive on the technologically promising silicon carbide (SiC) platform mainly due to difficulties in finding a resonance overlap between the magnonic system and the spin centers. Here we circumvent this challenge by harnessing nonlinear magnon scattering processes in a magnetic vortex to access magnon modes that overlap in frequency with silicon-vacancy ($\textrm{V}_{\mathrm{Si}}$) spin transitions in SiC. Our results offer a route to develop hybrid systems that benefit from marrying the rich nonlinear dynamics of magnons with the advantageous properties of SiC for scalable quantum technologies.
