A large scale quantum computer will require optical interconnects, regardless of the qubit platform, thus allowing a modular architecture with full connectivity. Atomic systems are natural memory nodes for photonic interfaces, especially atomic ions, which already feature high-performance local quantum gates and near-perfect initialization and measurement. There are several atom/photon interface prototols for heralded remote entanglement using photonic qubits encoded in polarization, frequency, or time-bin.
I will summarize recent advances in photonically-networked trapped ion systems. This includes progress on 3-node remote entanglement and the use of intervening SiV:diamond memory interfaces that will allow remote entanglement rates and fidelities to be as good as local entangement gates.
