Abstract:
We propose and analyse the implementation of high-fidelity, phonon-meditated gate operations and quantum simulation schemes for spin qubits associated with silicon vacancy centers in diamond. Specifically, we show how the application of continuous dynamical decoupling techniques can substantially boost the coherence of the qubit states and increase the cooperativity. We identify different regimes for this coherence enhancement, depending on the intensity of the driving and the strength of the noise. Our analytical and numerical studies show that this technique can be used to suppress gate errors by more than two orders of magnitude and to reach gate infidelities of 10-4 for experimentally relevant noise parameters
