Interfaces between color centers and photons

Quantum networks enable a broad range of practical and fundamental applications spanning distributed quantum computing through sensing and metrology. A key element of such networks is an interface between photons and stationary quantum memories--qubits. I will first present the recent results on coupling the Silicon-Vacancy color centers in diamond to photons via nanophotonic cavities. Next, I will introduce a novel approach based on nano-optomechanics which we use to control electron spins of the Nitrogen-Vacancy centers in diamond with telecom photons at room temperature. The latter method does not involve qubit optical transitions and is insensitive to spectral diffusion. This approach can be applied to a broad range of solid-state qubits and paves the way to hybrid quantum networks.
