摘要
We propose a fast scalable optical design for single and two-qubit gates for defect qubits in diamond (NV centres) and in silicon carbide, which are promising candidates for room temperature quantum computing. Two-qubit gates are mediated by microcavity photons that are coupled to optical transitions in these systems. Single-qubit operations are based on optically-assisted selectivity of microwave control. This approach does not require tunability of electronic transitions of the defects, and the cavity mode frequency remains off-resonance with the optical transitions at all times. The gates are controlled by near-resonant narrow-bandwidth optical pulses. We perform full quantum numerical modelling of the proposed gates and show that high fidelities can be obtained.
