In solid state spin-photon interfaces, a key challenge is to efficiently prepare the excited state while spectrally separating excitation light from the emitted photons. Here the authors demonstrate optical control of a spin center in diamond with both resonant driving and the SUPER nonresonant excitation based on two detuned pulses, and propose a broadband excitation protocol for spin-spin entanglement generation.
