Quantenbit operates segmented micro-structured Paul traps for scalable trapped-ion quantum information and, increasingly, for quantum sensing. Directions: (i) trapped Rydberg ions -- combining the tight confinement of a Paul trap with the giant polarizability of Rydberg states, which is simultaneously a fast-gate resource and an extremely sensitive electric-field probe; (ii) motional-mode sensing of electric fields and surface noise; (iii) deterministic single-ion implantation, where a cold ion is extracted from the trap and implanted with nm-scale placement -- directly relevant to building NV/donor arrays with known ion counts, and to single-ion detection validation; (iv) TACTICa, applying ion-trapping and quantum-logic spectroscopy to 229Th toward a nuclear clock; (v) single-atom heat engines and quantum thermodynamics. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), the deterministic-implantation line is the natural upstream complement: it is the route to engineering NV ensembles/arrays with controlled density rather than relying on stochastic implantation. Strong local coupling to Budker (Th-229, exotic physics) and Wendt (laser ionization).
Schneider leads the Many-Body Quantum Dynamics group. His primary work is on optical lattice quantum simulation with ultracold atoms (quasicrystalline and kagome potentials, non-equilibrium dynamics), but he also co-leads a significant quantum sensing arm: he is a core Cambridge PI in the AION collaboration building a 10 m strontium single-photon atom interferometer at Oxford and contributing to MAGIS-100 at Fermilab, targeting mid-band gravitational wave detection and ultralight dark matter. In 2026 he co-leads the UKRI-funded SEQUIN project, a hybrid quantum-classical interferometer array combining atom interferometry with seismometers to probe gravitational waves and Earth's interior.
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.
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. 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.
Simmons pioneered atomic-precision fabrication in silicon: hydrogen-resist STM lithography, phosphine dosing and epitaxial silicon overgrowth to place individual dopant atoms with sub-nanometre accuracy, then measure them at millikelvin. The programme has produced single-atom transistors, precision dopant arrays used as analogue quantum simulators, and the largest atom-scale device platform in the world; she also founded Silicon Quantum Computing Pty Ltd. The sensing-relevant capability is the single-electron transistor as an exquisitely sensitive electrometer, capable of resolving individual charge transitions and mapping local electrostatic potential at the atomic scale. 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 SET electrometry is the charge-domain counterpart to magnetic NV sensing at pT/sqrt(Hz): both are single-quantum-object detectors whose performance is limited by back-action and by the noise of the readout chain. Very large group, strongly fabrication-oriented and commercially entangled, which cuts against the stated preference for sensitivity-limited rather than fabrication-limited work.
Simpson runs the experimental quantum imaging and sensing laboratory at Melbourne and is the closest match at this institution to a bio-oriented NV sensing postdoc. Two active threads: (i) widefield NV magnetic and spin-relaxation imaging of living cells and tissue, including magnetic imaging of magnetotactic bacteria, cellular free radicals and paramagnetic ion transport, and quantum-probe imaging of neuronal activity; and (ii) engineering Australia's most sensitive diamond vector magnetometer with RMIT and Phasor Innovation, aimed at navigation, underground/undersea sensing and, explicitly, mapping magnetic signals of the human brain in unshielded environments. That second thread is a direct bid at bioelectromagnetism with a quantum sensor. 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 — Simpson's work is a continuation of exactly that lineage, pushing ensemble DEER/T1-relaxometry contrast mechanisms out of the physics lab and into cell biology and human-scale magnetoencephalography. Preferred attributes present: bioelectromagnetism, human-subject ambitions, sensitivity-limited (not fabrication-limited) programme. QUBIC investigator; recruits postdocs regularly.
