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.

McCamey is, for a candidate coming from NV ensemble sensing, the single most methodologically adjacent PI at UNSW. His laboratory does optically and electrically detected magnetic resonance on spins that are not defects in diamond: photogenerated spin-correlated radical pairs, triplet excitons in organic semiconductors, singlet-fission intermediates, and molecular spin systems. The instrumentation is the same toolkit — pulsed EPR, ODMR, dynamical decoupling, relaxometry — applied to systems where the spin is created by light and reports on chemistry. He directs the UNSW node of ARC Exciton Science. 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 — his group runs precisely those pulse sequences (Hahn echo, DEER, relaxometry) on a different spin species, and radical-pair spin chemistry is one of the few plausible mechanisms by which biology could be genuinely quantum — which makes this a strong landing spot for someone wanting to keep the NV skill set but change the physical system. Preferred attributes present: sensitivity-limited spin measurement, quantum-biology relevance.

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.

Weil directs the Synthesis of Macromolecules department at the MPI for Polymer Research in Mainz (co-located with JGU, with which the department collaborates closely). The quantum-sensing core of her programme is nanodiamond: in 2026 her group published a bottom-up route that converts molecularly defined nanographenes into ultrasmall, size-uniform nanodiamonds under HPHT, incorporating SiV and GeV colour centres during synthesis rather than by post-hoc implantation -- addressing the long-standing problem that milled detonation nanodiamonds have poor size control and damaged surfaces. Alongside this sits a mature nanodiamond biosensing line: surface bioconjugation and nanogel encapsulation, T1 relaxometry for free-radical detection in single mitochondria and in cells, nanoscale thermometry and photothermal theranostics. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this group is attacking the material bottleneck directly -- if you want NV/SiV ensembles with controlled size, surface and coherence for in-cell sensing, this is the synthesis end of that pipeline, and it feeds spin-readout collaborators at Ulm (Jelezko/Kubanek).

Xu leads the Experimental Quantum Engineering group with a joint ETH–PSI appointment. Research directions: (1) Superconducting circuit quantum sensing — using qubits-as-sensors for detecting weak microwave signals beyond standard quantum limits, quantum non-demolition readout of photon fields; (2) Quantum error correction enabled sensing — integrating bosonic codes (cat qubits, binomial codes) into sensing protocols; (3) Quantum acoustics — coupling superconducting qubits to surface acoustic wave (SAW) resonators for hybrid quantum sensing; (4) Novel quantum hardware at PSI — leveraging PSI's infrastructure for cryogenic device fabrication and testing.
