摘要：

频率转换是光学与电子学非线性系统中广泛实现的物理过程。作为一种新兴的非线性平台，自旋电子器件有潜力实现更强的频率转换。在此，我们展示了一种混合量子系统中的微波频率转换方法，该系统将金刚石中的氮-空位中心与磁性薄膜CoFeB集成在一起。我们实现了0.1至12 GHz的转换带宽，展示了高达第25阶的频率转换，并进一步展示了该方法在频率检测和量子比特相干控制中的应用。不同于基于非线性电响应的传统频率转换技术，我们的方法利用了自旋电子器件中的非线性磁响应。这种非线性源于磁膜中畴壁等对称性破缺，表明我们的方法可以适配其他自旋电子器件和自旋量子比特的混合系统，从而扩展自旋电子器件的应用范围，并为耦合量子系统提供一个有前景的片上平台。

英文摘要：

Frequency conversion is a widely realized physical process in nonlinear systems of optics and electronics. As an emerging nonlinear platform, spintronic devices have the potential to achieve stronger frequency conversion. Here, we demonstrated a microwave frequency conversion method in a hybrid quantum system, integrating nitrogen-vacancy centers in diamond with magnetic thin film CoFeB. We achieve a conversion bandwidth ranging from 0.1 to 12GHz, presenting an up to $\mathrm{25^{th}}$ order frequency conversion and further display the application of this method for frequency detection and qubits coherent control. Distinct from traditional frequency conversion techniques based on nonlinear electric response, our approach employs nonlinear magnetic response in spintronic devices. The nonlinearity, originating from the symmetry breaking such as domain walls in magnetic films, presents that our method can be adapted to hybrid systems of other spintronic devices and spin qubits, expanding the application scope of spintronic devices and providing a promising on-chip platform for coupling quantum systems.
