Towards microwave-to-optical conversion in magneto- optical resonators

Implementing microwave frequency qubits in future quantum networks will require coherent interconversion between single optical and microwave photons. Recent progress towards this goal has been made in cavity optomechanics, where the position of a mesoscopic object modulates the frequency of both microwave and optical cavities [1]. To compliment optomechanics, it may be worth considering alternative collective modes that could be coupled to optical and microwave systems in a similar way. The magnetization dynamics in ferromagnetic materials represents one such possibility. Here we explore the prospects of using magnetooptical resonators to achieve microwave-to-optical conversion.
