Schuessler combines optical frequency combs with cavity-enhanced and mid-IR spectroscopy for ultrasensitive trace-gas and isotopic detection, and runs ion-trap precision mass/laser spectroscopy of exotic species. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is a comb-metrology counterpart to spin-based chemical sensing.
A pioneer of circuit quantum electrodynamics, Schuster's group uses superconducting qubits and microwave resonators both as quantum-information platforms and as ultra-sensitive quantum-limited sensors/spectrometers, extending qubit-based readout to precision spectroscopy of otherwise inaccessible microwave-frequency phenomena.
Schwab's group studies quantum limits of nanomechanical and electromechanical measurement, coupling mechanical resonators to superconducting circuits and qubits to explore back-action-evading measurement, ground-state control, and force/displacement sensing at the quantum limit. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
Scott uses and develops 4D-STEM (scanning nanobeam electron diffraction) and other advanced electron-microscopy modalities, including energy-filtered techniques, to map short-range structural order and local diffraction signatures in quantum and semiconductor materials at the nanoscale.
Scully directs IQSE and pursues foundational quantum optics: quantum coherence effects (lasing without inversion, electromagnetically induced transparency), collective/superradiant emission, quantum-enhanced spectroscopy, and coherent-Raman schemes (FAST CARS) for real-time detection of pathogens and molecular fingerprints. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work sits on the fundamental-light side, providing coherence and superradiance concepts that inform quantum-enhanced magnetometry read-out.
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.
Prof. Shahriar's group uses atomic and optical systems for precision measurement and quantum information. Key directions: (1) White-light cavities — using anomalous dispersion media inside optical cavities to create a bandwidth-extended cavity enabling broadband gravitational wave detector sensitivity enhancement beyond current LIGO designs; (2) Superluminal (fast-light) gyroscopes — anomalous-dispersion-enhanced ring-laser gyroscopes for measuring the Lense-Thirring frame-dragging effect as a test of general relativity, with >10⁶× sensitivity enhancement over conventional Sagnac gyroscopes; (3) Quantum memories and computers using trapped atomic ensembles (PRISM protocol); (4) Ultra-low-light nonlinear optics with nanofibers and atoms for optical switching and quantum logic; (5) Holographic and polarimetric image processing. Member of LIGO Scientific Collaboration; contributed to GW170817 binary neutron star merger discovery. AT&T Professor of ECE.
Shutt co-founded the CDMS/SuperCDMS cryogenic solid-state dark-matter detector program and is a leader of the LZ liquid-xenon experiment, developing ultra-sensitive detectors for direct dark-matter detection at the single-quantum level.
Siddiqi's Quantum Nanoelectronics Laboratory develops superconducting quantum circuits and near-quantum-limited parametric amplifiers for qubit readout, quantum feedback, and quantum-enhanced sensing, and directs cross-campus quantum information efforts at Berkeley and LBNL.
