Here we discuss our work on an integrated thin-film lithium niobate platform to scale solid-state quantum emitters. We demonstrate state-of-the-art electro-optic devices including high efficiency couplers (~1.1dB / facet) and phase and intensity modulators with ultra-low half wave voltages (< 1 Vcm) and high bandwidths (> 40 GHz), all operating at near-infrared wavelengths. With these devices we classically demonstrate path switching of laser pulses with extinction ratios beyond 20 dB and frequency shifting of continuous-wave light beyond 10 GHz. We finally discuss progress towards spatial- and frequency-mode shifting of single photons emitted from atomic defects in diamond.
