Anders designs integrated-circuit quantum and magnetic-resonance sensors: EPR-on-a-chip (single-chip ESR spectrometers reaching ~1e9 spins/sqrt(Hz)), chip-scale NMR relaxometry for point-of-care, and CMOS/SiGe-integrated diamond NV magnetometers - miniaturizing spin sensing onto silicon. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is the integrated-circuit route to deployable NV/EPR ensemble sensing.

Ardavan leads the Quantum Spin Dynamics group, studying quantum coherent phenomena in condensed matter. Central to the lab's quantum sensing relevance: (1) molecular spin qubits — using pulsed EPR/DEER to characterise and control multi-spin registers ({Cr7Ni} molecular rings, nitroxide radical chains) assembled into qubit networks, measuring coherence times, inter-qubit couplings, and demonstrating spin-electric coupling in molecular magnets; (2) DNA-assembled molecular quantum devices — using DNA nanostructures to precisely position molecular spin qubits for multi-qubit sensing and quantum information applications; (3) surface atom spin resonance — STM-based coherent spin control of individual atoms on surfaces at nanosecond timescales. Uses X-band through W-band pulsed EPR at Centre for Advanced Electron Spin Resonance (CAESR), Oxford.

Bowen leads the CQSE 'Spins and Qubits' theme at Manchester, focusing on organometallic molecular spin qubits for quantum sensing and computing. Research directions: (1) Organometallic La(II) and other rare-earth molecular qudits — designing molecules with multiple accessible spin states (qudits) for encoding quantum information and sensing; (2) Pulsed EPR characterization — Hahn echo, ESEEM, ENDOR at X/W/Q-band to measure coherence times and hyperfine couplings; (3) Integration of molecular qubits into devices — surface deposition and nanoscale addressing; (4) Multi-spin sensing — using exchange-coupled spin pairs as differential sensors of magnetic field gradients. Closely collaborates with Tuna and Winpenny.

The Han Lab (Chemistry, joined fall 2023) develops quantum sensing tools rooted in electron and nuclear spin physics for life-science applications. Directions: (1) DNP-enhanced NMR quantum sensing using coupled electron-nuclear spin clusters — designing novel biradical and multi-spin systems achieving 700-fold ¹³C signal enhancement at 14.1 T via P1 center clusters in HPHT diamond (exchange coupling >100 MHz); aiming for in-cell NMR with sensitivity to track water dynamics in a single cell; (2) High-field pulsed EPR at 240 GHz / 8.6 T: time-resolved Gd-Gd EPR (TiGGER) for tracking inter-residue distances during protein functional cycles in solution with sub-nm resolution; rapid-scan field-domain EPR development; (3) Integration of DNP/EPR with nanodiamond-based quantum sensors: coupled electron-nuclear spin cluster design for long-range quantum sensing in biological environments, bridging conventional NMR/EPR and NV-center-based quantum sensing. Han directs the EPR/DNP component of IMSERC (Northwestern's core facility) and brought three new EPR spectrometers and a 600 MHz DNP-NMR system.

Hoffman develops and applies electron-nuclear double resonance (ENDOR) spectroscopy -- a combination of EPR and NMR -- to resolve individual hyperfine-coupled nuclei at metalloenzyme active sites with atomic-scale precision, work that has revealed mechanisms of nitrogenase nitrogen fixation, radical-SAM enzyme catalysis, and copper/methane monooxygenase chemistry. The technique pushes magnetic-resonance spectroscopic resolution well past what conventional EPR can resolve, in a manner methodologically continuous with molecular spin-qubit sensing.

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.

McInnes leads the National EPR Facility at Manchester (Europe's broadest EPR suite) and researches molecular spin qubits. Research directions: (1) Pulsed EPR spectroscopy of molecular spin systems — Hahn echo, ESEEM, ENDOR, DEER for structural and electronic characterization of inorganic and organometallic complexes; (2) Molecular spin qubits — [Cu(mnt)2]²⁻ and related molecules as candidate qubits; measuring coherence times and investigating decoherence mechanisms; (3) Multi-qubit molecular registers — using exchange interactions for two-qubit gates within a molecule; (4) Magnetic sensing applications — molecular systems for magnetic field sensing below the diffraction limit. Partner of NPL M4Q EPSRC Network for Materials for Quantum.

Pla is the strongest single match in this cohort for a candidate whose background is sensitivity-limited spin detection. His laboratory does inductively-detected electron spin resonance at millikelvin using high-quality-factor superconducting microresonators, read out through Josephson and travelling-wave parametric amplifiers operating at the quantum limit of added noise. The result is ESR sensitivity improved by many orders of magnitude over commercial spectrometers — the group's stated target is single-spin inductive detection — and, in parallel, the development of near-ideal degenerate parametric amplifiers and squeezed microwave states as the readout resource that makes it possible. Applications explicitly include chemistry and biology, where the goal is to do EPR on samples far too small for a conventional spectrometer. 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 microwave-inductive route to the same destination: where an NV ensemble reaches pT/sqrt(Hz) by optical readout of many spins, Pla reaches comparable or better spin sensitivity by making the microwave detection chain quantum-limited, and the DEER and dynamical-decoupling sequences are shared verbatim. Preferred attribute present in the strongest form: cutting-edge sensitivity, not device fabrication, is the object.

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.
