To realize a quantum internet, a quantum transducer that connects microwave photons from superconducting qubits to optical fiber communication is required. In this work, we design a diamond optomechanical cavity embedding NV centers for efficient microwave-to-telecom wavelength conversion. Finite-element simulations show that the cavity achieves an optical Q factor of 1.5 x10^4 and a mechanical Q factor of 3.8 x10^6. The conversion efficiency will also be discussed.
