Abstract
Section titled āAbstractāGenerating\nentangled graph states of qubits requires high entanglement\nrates with efficient detection of multiple indistinguishable photons\nfrom separate qubits. Integrating defect-based qubits into photonic\ndevices results in an enhanced photon collection efficiency, however,\ntypically at the cost of a reduced defect emission energy homogeneity.\nHere, we demonstrate that the reduction in defect homogeneity in an\nintegrated device can be partially offset by electric field tuning.\nUsing photonic device-coupled implanted nitrogen vacancy (NV) centers\nin a GaP-on-diamond platform, we demonstrate large field-dependent\ntuning ranges and partial stabilization of defect emission energies.\nThese results address some of the challenges of chip-scale entanglement\ngeneration.
