Mikhail Lukin's group at Harvard works across four overlapping fronts: silicon-vacancy (SiV) and nitrogen-vacancy (NV) colour-centre networking with diamond nanophotonic cavities; neutral-atom programmable simulators scaled to hundreds of atoms via optical tweezers and Rydberg interactions, including logical-qubit fault-tolerance demos; quantum-repeater prototypes, most recently 35 km telecom-fibre entanglement of two SiV memory nodes on a Boston-area loop (Knaut et al. 2024); and single-NV magnetometry. Current networking thrust: extending SiV-cavity nodes from two-node to multi-node telecom links.

Current focus: Quantum optics, AMO physics and quantum networking
