To operate and store continuous-variable (CV) quantum states with high fidelity, a quantum interface connecting light and quantum memory is essential. In this study, we propose a method to transfer a generated CV spin state to an optical state by coupling an ensemble of solid-state spin defects with microwave and optical cavities, and investigate the system theoretically and numerically. In the presentation, we report the relaxation suppression effect via dynamical decoupling, and present specific requirements for the cavities, such as coupling strengths and Q factors.
