John Rarity's group works on quantum-enhanced measurements and free-space quantum key distribution. Research: (1) quantum imaging with undetected photons — mid-infrared gas sensing (CO2, CH4) exploiting entangled photon pairs, with only near-IR photons detected (startup QLM); (2) sub-shot-noise imaging using quantum-identical photon beams; (3) spin-photon interfaces (1D cavity with near-unit scattering efficiency); (4) compact satellite QKD transmitters (EPSRC Quantum Comms Hub). Highly relevant to quantum-enhanced sensing.

Uses single-molecule spectroscopy, optical trapping, and advanced imaging to study nanoscale systems. Directions: (1) orientation-resolved single-molecule spectroscopy using polarization-controlled excitation and detection; (2) optical trapping of individual nanoparticles and viruses to study force-dependent dynamics; (3) plasmon-enhanced single-molecule detection and imaging beyond diffraction limit; (4) ultrafast spectroscopy of nanoscale energy transfer.

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.

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.

Sokolov develops femtosecond adaptive spectroscopic techniques for coherent Raman (FAST CARS), broadband stochastic laser fields, and quantum-light probes of molecular coherence for standoff chemical/biological sensing and label-free imaging. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work contributes ultrafast coherent-Raman methodology adjacent to spin-based sensing.

Research centers on manipulating and measuring single molecules with quantum-level precision. Primary platform: ABEL trap (Anti-Brownian ELectrokinetic trap) for single-molecule confinement in free solution without surface tethering, enabling measurement of spectroscopic identity, molecular dynamics, and nanoscale energy transfer at femtomolar concentrations. Also develops orientation-resolved single-molecule imaging and single-molecule FRET for photoadaptation in photosynthetic systems and nanoscale immune cell signaling. QuBBE member.

The Stern Group explores fundamental quantum interactions of photons with 2D materials, nano-scale structures, and atoms. Key thrusts: (1) Valley-selective exciton-polaritons in monolayer transition-metal dichalcogenides (MoS₂, MoSe₂, WSe₂) embedded in optical microcavities — hybrid light-matter quasiparticles with valley-selective polarization and cavity-modified dynamics; (2) 2D semiconductor quantum emitters — quantum-dot-like single-photon emitters formed by confinement in TMD nanoribbons and by chemical functionalization/strain engineering of defects; (3) Astrophotonics: collaboration with Argonne National Laboratory and the Australian Astronomical Observatory to design and fabricate silicon ring-resonator photonic circuits for OH sky-background suppression in near-IR astronomical spectrographs; (4) Quantum non-reciprocal photonics in axisymmetric microresonators. Experimental tools: time-resolved spectroscopy, single-photon counting, nanofabrication. DOE Early Career Award; ONR Young Investigator Award; Sloan Research Fellow 2013.

van Loock leads theoretical quantum optics and quantum information at Mainz, with a long-standing focus on continuous-variable quantum optics: squeezed and other nonclassical Gaussian states, non-Gaussian resources such as cat and GKP states, hybrid discrete/continuous-variable encodings, and the error-correction and repeater architectures built on them. The group also works on the fundamental limits of quantum-enhanced measurement and on how nonclassical light can be used as a metrological resource. He is theory-first, with output that directly serves the experimental quantum-optics and trapped-ion groups in Mainz. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), the relevance is on the fundamental-light-physics axis rather than the magnetometry axis: this is where the squeezing/nonclassical-state theory sits that would let a spin-ensemble sensor beat the standard quantum limit.

PREFERRED. Vuletic's group generates large-scale spin squeezing and entanglement in cold and ultracold atomic ensembles to push optical atomic clocks and rotation/field sensors below the standard quantum limit, alongside work on cavity QED, Rydberg tweezer arrays, and nonlinear quantum optics at the single-photon level. Recent work includes cavity-feedback spin squeezing for ytterbium clocks and fault-tolerant neutral-atom quantum sensor/processor arrays with collaborators at Harvard.

Windpassinger's group works on cold neutral atoms as both a platform for fundamental light-matter physics and a deployable sensing technology. The fundamental line uses dysprosium -- the most magnetic element -- to study light propagation in dense dipolar media, where interatomic spacings fall below the optical wavelength and light-induced plus magnetic dipole-dipole interactions produce cooperative effects (superradiance, subradiance); controlled transport in optical dipole traps and microfocusing let them tune from single-atom to collective behaviour. The applied line builds ultracold-atom quantum sensors that survive outside the lab: atom interferometers and BEC sources flown in the Bremen drop tower, on sounding rockets, and on the ISS, aimed at inertial sensing, gravimetry and tests of fundamental constants under microgravity. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is the complementary 'cold and fragile but absolutely calibrated' end of the sensing spectrum; the group's real distinguishing asset for a postdoc is the space/microgravity engineering pipeline, which is rare. The group states it is continuously looking for motivated researchers and lists open positions via the PI.
