Hogan's group studies atoms and molecules in high Rydberg states for precision measurements and quantum sensing. Research directions: (1) Rydberg atom electric field sensing — Rydberg atoms exhibit enormous electric polarizabilities; Stark-map and EIT-based electrometry with sub-mV/cm sensitivity and GHz-range frequency coverage; (2) Rydberg molecule spectroscopy — long-range Rydberg molecules as probes of intermolecular forces; (3) Stark deceleration and trapping of Rydberg atoms/molecules — producing cold samples for precision spectroscopy and scattering experiments; (4) Circular Rydberg states — extremely long-lived states for quantum information storage and sensing. Collaborates on quantum-enhanced sensing of RF/microwave fields.

Home leads the TIQI group working with Be+ and Ca+ trapped ions. Research directions: (1) Quantum error correction — fault-tolerant gates, surface code implementations with multi-ion chains; (2) Precision metrology — ytterbium ion optical clock, mixed-species ion chain spectroscopy and ytterbium HFS measurements; (3) Macroscopic superposition and quantum contextuality — creating nonclassical motional states in harmonic oscillators for tests of quantum foundations; (4) Scalable architectures — photonic integrated waveguides for individual ion addressing, quantum logic detection of spectroscopy ions. Key publications include first two-qubit gates with mixed species and records in quantum state readout fidelity. Lab is investigating quantum logic-enhanced spectroscopy of complex atomic systems.

Knowles leads the Coherent Quantum Lab at the Cavendish Laboratory. Her research focuses on using NV centers in diamond as quantum sensors to probe matter at the nanoscale in two main thrusts: (1) nanoscale NMR / spin imaging — scanning-probe NV magnetometry of topological and unconventional magnets, Hamiltonian engineering in dense spin ensembles using global dynamical decoupling, and error-correction-enhanced sensor readout; (2) quantum biosensing in living systems — employing diamond nanocrystals functionalized for intracellular delivery to perform simultaneous nanothermometry and nanorheometry in single HeLa cells and C. elegans, using the Q-BiC integrated biocompatible chip platform. She co-leads CANSIS. The lab has a second new instrument running since mid-2025 for biosensing experiments.

Laucht works on the quantum control of spins across two platforms: donor spin qubits in silicon (with Morello and Dzurak), where he demonstrated electrically-driven single-spin control in a continuous microwave field and pioneered dressed-state protection against decoherence; and, more recently, spin defects in hexagonal boron nitride — a 2D material whose optically addressable spin defects are the most promising candidate for a van der Waals analogue of the NV centre, with the enormous advantage that the sensor can be placed a single atomic layer from the sample. 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 — hBN spin defects are the field's most active attempt to beat the standoff-distance limitation that caps near-surface NV ensemble sensitivity; a candidate with NV ODMR experience would be immediately productive here, running the same pulse sequences on a new defect. Strong fit.

Develops quantum sensing platforms at the biology interface. Core NV-center work: (1) widefield NV magnetic imaging of action potentials in neurons and cardiac tissue; (2) NV-based single-molecule NMR at 14 T resolving molecular structure with single-molecule sensitivity; (3) charge-sensitive shallow NV nanoprobes monitoring real-time cellular electrophysiology; (4) biocompatible diamond surface functionalization enabling multiplexed DNA microarray biosensing; (5) fluorescent-protein spin qubits as biological alternatives to diamond NV (2025 paper, Physics World Top-10 Breakthrough). Runs full NV stack: hot implantation, widefield and confocal ODMR, T1/T2/Hahn echo/DEER/Rabi, automated fitting pipelines. 2026 Sloan Fellow. PhD Lukin/Harvard; postdoc Chu/Stanford. Argonne joint appointment.

Morello heads the Fundamental Quantum Technologies Laboratory and is the person who first read out the spin of a single electron, and then a single nucleus, in silicon. Current directions: high-spin donors (antimony-123, with eight nuclear levels) used as qudits and as sensors of local strain and electric field; nuclear acoustic resonance, in which a strain wave rather than a magnetic field drives the nuclear spin; engineered decoherence experiments as tests of quantum foundations; and precision tomography of multi-qubit donor registers. The group's donors are among the longest-coherence solid-state spins known (seconds for nuclei). 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 — a single-donor nuclear spin in silicon is functionally an NV centre with better coherence and worse readout: the same DEER, dynamical-decoupling and nuclear-register protocols apply, and the group's high-spin qudit work is aimed at exactly the multi-level sensing enhancements that the NV community is now chasing. Preferred attribute present: sensitivity and coherence, not fabrication, are the limiting variables here.

The Odom Group studies trapped molecular ions at millikelvin temperatures using radio-frequency ion traps. Key directions: (1) Controlled preparation and single-quantum-state readout of trapped molecular ions (e.g., AlH⁺, SiO⁺, N₂⁺) — combining laser cooling, blackbody-radiation-assisted state preparation, and fluorescence detection for single-molecule precision spectroscopy; (2) Search for time-variation of fundamental constants (electron-to-proton mass ratio, fine structure constant α) using molecular vibrational/rotational transitions as highly sensitive probes; (3) Quantum effects in sub-Kelvin chemistry — probing tunneling, orbiting resonances, and quantum state control of reactive collisions between cold molecules. Member of CFP Northwestern.

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).

Tan trained at NIST Boulder in the Wineland lineage and brought quantum-logic spectroscopy and entanglement-enhanced metrology to Sydney. His independent programme builds trapped-ion systems for quantum simulation of vibronic and chemical dynamics, for bosonic/qudit encodings, and — most relevant here — for precision measurement that exploits entangled states to beat the standard quantum limit. The group also works on high-fidelity gates and on using motional modes as sensitive transducers of weak forces and electric fields. 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 — entanglement-enhanced protocols are the natural next step beyond the shot-noise-limited pT/sqrt(Hz) ensemble measurements that define the current NV state of the art, and Tan is one of a small number of Australian PIs actually implementing them. Mid-career, actively building; a strong option for a candidate wanting to move from spin ensembles to entangled sensors.

Wolf works on trapped-ion quantum sensing, using the motional degrees of freedom of single ions and small crystals as transducers for weak electric fields and forces, together with non-classical motional states (squeezed and Fock states) to enhance the achievable sensitivity. The broader agenda is to use trapped ions as a testbed for fundamental measurement limits — quantum-enhanced amplification of small displacements, quantum non-demolition readout of motion — with an eye to applications in electric-field metrology and searches for new physics. 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 — trapped-ion motional sensing is the cleanest available platform for demonstrating the entanglement-enhanced scaling that NV ensembles at pT/sqrt(Hz) approach only in the shot-noise-limited regime. Early-career independent PI within the Quantum Control Laboratory; smaller group, higher autonomy.
