Levine builds neutral-atom tweezer-array and superconducting-qubit platforms for quantum computing, quantum error correction, and quantum sensing, aiming to combine the programmability of Rydberg arrays with new approaches to distributed and networked quantum sensing. The group is actively recruiting postdocs.
Lukin's group is a leading center for quantum science built on NV- and SiV-center diamond spin qubits, neutral-atom (Rydberg) tweezer arrays, and hybrid quantum networks, spanning quantum sensing, quantum information processing, and many-body physics. This work builds directly on the lineage of NV ensemble quantum sensing experiments (DEER, nanoscale NMR, T1 relaxometry) that first reached pT/√Hz-class magnetic sensitivities, which Lukin's own group helped pioneer and continues to extend toward nuclear-spin-register-based nanoscale NMR and distributed sensor networks.
Semeghini is an experimentalist studying quantum simulation of complex materials using Rydberg-atom tweezer arrays; she joined the SEAS Applied Physics faculty after a postdoctoral appointment in Mikhail Lukin's group. Included as a borderline, not-preferred case: the Rydberg-tweezer platform overlaps with quantum-sensing hardware, though her stated focus is quantum simulation rather than sensing per se.
Pascale Senellart's group at C2N develops the world's most efficient and bright quantum dot single-photon sources. Research: (1) high-efficiency single-photon emitters based on semiconductor quantum dots in micropillar cavities — up to 99% efficiency, >98% photon purity; (2) entangled photon pair sources; (3) photonic integrated circuits for quantum information and sensing. Coordinator of Quantum-Saclay ecosystem; co-founder of Quandela (quantum photonics spinoff). Key for quantum sensing with non-classical light.
