Towards Networked Quantum Memories on Photonic Integrated Circuits

We discuss progress towards the development of on-chip quantum networks of multiple spin qubits in nitrogen vacancy (NV) centers in diamond. This talk will describe NV-nanocavity systems in the strong Purcell regime with optical quality factors approaching 10,000 and electron spin coherence times approaching milliseconds; implantation of NVs with nanometer-scale apertures into the cavity field maximum; hybrid on-chip networks for integration of multiple functional NV-cavity systems; and techniques for high-yield integration of superconducting nanowire single photon detectors on-chip.
