  Large scale control over thousands of quantum emitters desired by quantum
network technology is limited by power consumption and cross-talk inherent in
current microwave techniques. Here we propose a quantum repeater architecture
based on densely-packed diamond color centers (CCs) in a programmable electrode
array. This 'electric-field programmable spin array' (eFPSA) enables high-speed
spin control of individual CCs with low cross-talk and power dissipation.
Integrated in a slow-light waveguide for efficient optical coupling, the eFPSA
serves as a quantum interface for optically-mediated entanglement. We evaluate
the performance of the eFPSA architecture in comparison to a routing tree
design and show increased entanglement generation rate into thousands of qubits
regime. Our results enable high fidelity control of dense quantum emitter
arrays for scalable networking.
