Bean's group designed, built, and operates MAROON-X, a fiber-fed, high-dispersion precision radial-velocity spectrograph on the 8m Gemini-North telescope, achieving sub-m/s-class radial-velocity precision to detect and mass-characterize small planets around nearby M dwarfs and to identify/refine targets for JWST atmospheric spectroscopy. This is an astronomy pivot from quantum sensing in the sense the filter intends: a purpose-built, cutting-edge-sensitivity spectrograph (rather than a quantum sensor per se) enabling detection at the edge of instrumental precision.
Boccaletti develops and exploits high-contrast coronagraphic imaging instrumentation for direct detection and characterization of exoplanets and circumstellar debris disks, including the four-quadrant phase-mask coronagraph built at Observatoire de Paris-PSL now flying on JWST's MIRI instrument, which recently resolved the inner dust belt and all four planets of the HR 8799 system in the mid-infrared.
Lagrange is a leading figure in direct-imaging exoplanet science, using the VLT/SPHERE extreme-adaptive-optics coronagraph (which she helped design and exploit) to detect and characterize young giant planets around nearby stars, most notably the beta Pictoris planetary system, and to study debris-disk and planet-formation signatures such as non-common-path aberration correction algorithms for next-generation direct-imaging instruments.
Queloz (2019 Nobel Prize, co-discoverer of 51 Peg b) leads exoplanet research at Cambridge, including precision radial velocity spectrograph development and transit photometry. He chairs the CHEOPS space mission science team and is founding director of the Leverhulme Centre for Life in the Universe at Cambridge. Research focuses on characterizing transiting terrestrial planets (especially around M dwarfs including TRAPPIST-1) and atmospheric biosignature detection with JWST-era instruments. Part-time appointment at University of Geneva.
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.
NON-PREFERRED (astronomy pivot, kept for review). Seager's group works on exoplanet atmosphere and interior characterization and the search for atmospheric biosignature gases, including leadership of space-mission concepts (Starshade, ASTERIA, TESS deputy science direction) that require high-contrast, high-resolution spectroscopic instrumentation; per public reporting she is departing MIT for the University of Toronto/CITA effective September 1, 2026, so any postdoc search should confirm her host institution directly.
Szentgyorgyi builds high-dispersion optical spectrographs for precision radial-velocity exoplanet detection and stellar spectroscopy, having worked across neutrino, gamma-ray, and X-ray astronomy before focusing the last two decades on next-generation precision spectrograph instrumentation.
Tinney is an exoplanet hunter who builds the spectrographs he uses. He leads Veloce, the high-resolution, ultra-stable echelle spectrograph on the Anglo-Australian Telescope, whose entire purpose is to measure stellar radial velocities at the ~1 m/s level — a fractional wavelength shift of order 10^-9 — which requires obsessive control of thermal, mechanical and illumination systematics plus laser-comb or etalon wavelength calibration. He also works on brown dwarfs and on disentangling stellar activity from planetary signals. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — precision radial velocity is a frequency-metrology problem dressed as astronomy: like a pT/sqrt(Hz) magnetometer, the instrument's raw sensitivity was solved years ago and all remaining progress is in systematics and calibration. Good pivot target for a metrology-trained candidate.
Trenti combines high-redshift galaxy and gamma-ray-burst science with hands-on space instrumentation: he leads SkyHopper, a 6U CubeSat carrying a cooled near-infrared telescope intended for rapid follow-up of transients and exoplanet transits, which is an unusually complete exercise in building a photon-starved instrument under severe SWaP constraints. The group also works on infrared detector characterisation and on-board autonomy. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — the relevance to a quantum-sensing candidate is the engineering discipline of getting a low-noise detector to work in a hostile, uncontrolled environment — the same problem that separates a laboratory pT/sqrt(Hz) NV magnetometer from a fieldable one. Borderline inclusion on the astronomy criterion; kept because instrumentation is a genuine focus rather than a by-product.
Tuthill is the world's leading practitioner of aperture-masking interferometry and its modern photonic successors. His group's instruments — GLINT (a photonic nuller that destructively interferes starlight on a chip), Dragonfly, and the kernel-phase analysis framework — exist to recover structure at and below the formal diffraction limit of the telescope, in the photon-starved, speckle-dominated regime where naive imaging fails. Science targets are the dusty pinwheel nebulae of Wolf-Rayet binaries, protoplanetary discs and direct detection of exoplanets. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — this is the astronomy entry in the search that most closely mirrors the intellectual structure of quantum sensing: the instrument's performance is set by a fundamental noise floor (photon and speckle noise, analogous to the shot-noise floor at pT/sqrt(Hz)), and the entire game is designing an estimator and a hardware front end that saturate it. Preferred attribute strongly present.
