Rimmer's Planetary Astrochemistry Lab experimentally simulates planetary atmospheric, aqueous and surface chemistry to measure reaction rate constants relevant to prebiotic chemistry, using the custom-built StarLab UV photochemistry simulator to reproduce the light of young stars, in order to constrain which planets and moons are most likely to host the chemical pathways to life.
Roberts leads Melbourne's optics group and is a chief investigator in the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS). The work is about extracting information that conventional intensity imaging discards: metasurface-encoded point spread functions that recover the full polarisation state or quantitative phase in a single shot, subwavelength structures for edge enhancement and optical computing, and vectorial beam shaping. For a quantum-sensing candidate the relevant hook is that meta-optics is becoming the standard way to miniaturise the optical front end of NV, atomic-vapour and single-molecule sensors, and to add orientational sensitivity to imaging. 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 — her metasurface collection optics and polarisation-resolved detection schemes are being applied to improve photon collection efficiency and orientational discrimination in exactly the NV-ensemble geometries used for pT/sqrt(Hz) magnetometry. Preferred attribute present: orientation-resolved methods that push past standard resolution limits.
Jean-François Roch (Professor at ENS Paris-Saclay, LuMIn) is a world leader in NV-center diamond quantum sensors. Research: (1) NV center magnetometry — scalar and vector magnetic field sensing with ensembles and single NV spins; (2) NV centers in diamond anvil cells for high-pressure magnetometry (world record 240 GPa); (3) joint laboratory (JRL) with Thales R&T on industrial NV quantum sensors; (4) color centres in hBN. IUF Senior Member 2021; Jaffé Prize + Berthelot Medal 2024.
Rock builds custom single-molecule fluorescence microscopes and optical tweezers to directly watch individual myosin motors move along the actin cytoskeleton in vitro and in living cells, quantifying motor stoichiometry, force generation, and navigation rules that organize cell shape and motility. Where NV-ensemble quantum sensors read out spin ensembles magnetically at pT/sqrt(Hz) sensitivity via DEER/NMR/T1 protocols, Rock's approach achieves single-fluorophore and single-motor mechanical/positional resolution using all-optical single-molecule methods.
Roessler uses continuous-wave and pulsed EPR/ENDOR spectroscopy to probe paramagnetic metal centres and radical intermediates in catalytic and bioinorganic systems, work that overlaps with the use of molecular spin centres as candidate EPR-addressable qubits/sensors.
Rogge (formerly Delft) works on the spectroscopy of individual dopant atoms in silicon: using transport, STM and microwave spectroscopy to read out the orbital, valley and spin structure of single donors and acceptors, including their coupling to strain, electric fields and each other. The group has mapped the wavefunctions of individual dopants and used acceptor spin-orbit coupling for electric-field-driven spin control. This is single-quantum-object measurement rather than device engineering. 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 — single-donor spectroscopy is the silicon analogue of single-NV work: the same questions about coherence, bath engineering and readout fidelity that fix pT/sqrt(Hz) ensemble performance appear here in a platform where the sensor can be placed with atomic precision and interrogated electrically rather than optically.
Romalis develops ultra-sensitive alkali-vapor magnetometers operating in the spin-exchange-relaxation-free (SERF) regime, K-noble-gas nuclear spin co-magnetometers used as gyroscopes and for electron/nuclear EDM and Lorentz-violation searches, and Rydberg-atom microwave electric-field sensors; his group's SERF magnetometers were the first used to detect brain magnetic fields. This continues and extends the historical arc of atomic and NV-ensemble quantum sensing (comparable in spirit to DEER/NMR/T1-relaxometry approaches reaching pT/sqrt(Hz) sensitivities), pushing scalar and vector magnetometry toward the fT/sqrt(Hz) and below regime through spin-squeezing and multi-pass optical cells.
Romanenko leads the Quantum Technology thrust at the SQMS Center, using ultra-high-coherence 3D niobium SRF cavities as both long-lived quantum memories for multimode superconducting quantum computing and as ultra-sensitive detectors for fundamental physics. He conceived and led the Dark SRF experiment, the first demonstration of SRF cavities used as light-shining-through-wall detectors, achieving new sensitivity limits for hidden-sector dark photons, and continues to explore SRF-based sensing of dark matter and gravitational waves.
Massimiliano Rossi's lab focuses on levitated systems, optical tweezers, and quantum measurement. Research: (1) optically levitated nanoparticles for force sensing and zeptonewton-scale measurements; (2) quantum measurement and control of levitated systems approaching the quantum ground state; (3) back-action-evading measurement schemes for levitated oscillators; (4) exploring quantum-to-classical transitions. The lab is developing levitated systems as sensors for dark matter and gravitational waves.
Roukes' group develops nanoelectromechanical systems (NEMS) for single-molecule mass sensing and resonant spectrometry, and large-scale neurotechnology platforms (including integrated neurophotonic probes) for recording brain activity, pushing mechanical and neural sensing toward single-analyte and single-neuron resolution. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
