Department(s)/lab(s): School of Physics | McCamey Spin Physics and ODMR Laboratory @ UNSW
Summary:

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 β€” pulsed EPR, ODMR, dynamical decoupling, relaxometry β€” 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 β€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity β€” 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 β€” 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.

Department(s)/lab(s): Physics | Quantum Measurement & Control Group @ Caltech
Summary:

McCuller develops quantum resources - squeezed light, non-Gaussian states (cat/GKP/photon-subtracted), and optomechanical amplifiers - to push interferometric measurement beyond the standard quantum limit; the group enabled LIGO's broadband frequency-dependent squeezing and is building integrated waveguide squeezers and quantum links for precision sensing. Actively recruiting students and postdocs. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.

Department(s)/lab(s): Physics | McDermott Group @ UWMadison
Summary:

Develops superconducting qubits and QND microwave single-photon detectors, applying them both to scalable quantum computing architectures and to axion/dark-photon dark-matter search experiments as ultra-sensitive quantum sensors.

Department(s)/lab(s): Physics & Astronomy | Quantum Technologies for Fundamental Physics Group (McDonald Group) @ Manchester
Summary:

McDonald leads the Quantum Technologies for Fundamental Physics (QTFP) theme at CQSE Manchester. Research directions: (1) Manchester Axion Novel Cavity eXperiment (MANCX) β€” building a cavity haloscope to search for QCD axions and axion-like particles coupling to photons via resonant microwave cavity enhancement at Manchester; (2) Astroparticle theory β€” superradiance from black holes for ultralight dark matter/axion bounds; neutron star probes of new physics; (3) Dark energy / extended gravity β€” vacuum energy and Casimir-type effects; (4) High-frequency gravitational waves β€” novel detection concepts. Workshop chair for Manchester's QTFP international workshop (Jan 2026). Interdisciplinary collaboration with quantum engineers, low-temperature physicists, and particle physicists.

Department(s)/lab(s): Chemistry – National Electron Paramagnetic Resonance Facility | National EPR Facility / McInnes Group @ Manchester
Summary:

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 β€” Hahn echo, ESEEM, ENDOR, DEER for structural and electronic characterization of inorganic and organometallic complexes; (2) Molecular spin qubits β€” [Cu(mnt)2]²⁻ and related molecules as candidate qubits; measuring coherence times and investigating decoherence mechanisms; (3) Multi-qubit molecular registers β€” using exchange interactions for two-qubit gates within a molecule; (4) Magnetic sensing applications β€” molecular systems for magnetic field sensing below the diffraction limit. Partner of NPL M4Q EPSRC Network for Materials for Quantum.

Department(s)/lab(s): Division of Medicine / London Centre for Nanotechnology | McKendry Group / London Centre for Nanotechnology (Q-BIOMED) @ UCL
Summary:

McKendry co-directs Q-BIOMED, the UK's national quantum-biomedical-sensing research hub (UKRI/NIHR, ~GBP24M), which brings NV-diamond and other quantum sensors into clinical diagnostics. Her own group has developed nitrogen-vacancy nanodiamond-labelled lateral-flow and rapid molecular tests -- including a quantum-enhanced SARS-CoV-2 antigen test and single-molecule HIV RNA detection -- that exploit resonant microwave control of the NV spin state to separate signal from background and push rapid point-of-care diagnostics toward single-molecule sensitivity, a direct human-diagnostics application of quantum sensing.

Department(s)/lab(s): Physics | McKinsey Lab @ UCB
Summary:

McKinsey develops ultra-low-background noble-liquid (xenon and argon) time-projection chambers for direct dark matter detection, including leadership roles on LZ, and works on quantum-sensor readout of scintillation and ionization signals to push detection thresholds toward single-quantum sensitivity.

Department(s)/lab(s): School of Physics / Institute of Photonics and Optical Science | Eggleton Research Group @ USyd
Summary:

Merklein is the independent PI within the Eggleton group most focused on the acoustic side of Brillouin physics: he demonstrated on-chip photon-phonon memory (coherently transferring an optical pulse into a long-lived acoustic excitation and back), and works on distributed Brillouin sensing in optical fibre and on the coherent control of travelling acoustic waves in waveguides. The distributed-sensing thread is a practical, sensitivity-limited measurement problem: recovering strain and temperature along kilometres of fibre from a very weak backscattered signal. Positioned against the established body of NV-ensemble quantum sensing work β€” DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity β€” phonon-mediated storage and readout is a complementary transduction channel to spin-based sensing, and the group is now pushing toward the quantum regime where the acoustic mode must be treated as a quantum object rather than a classical one. Early-career PI (DECRA) with genuine independence inside a large group.

Department(s)/lab(s): Department of Chemistry & Applied Biosciences (D-CHAB) – IMPS | Molecular Physics and Spectroscopy Group (Merkt) @ ETH Zurich
Summary:

Merkt leads the Molecular Physics and Spectroscopy group at ETH D-CHAB. Research directions: (1) High-resolution XUV/VUV spectroscopy β€” using synchrotron radiation and table-top laser sources to study molecular Rydberg states, ionization thresholds, and ro-vibrational structure at sub-MHz precision; (2) Precision molecular clock transitions β€” proposing and measuring molecular transitions suitable for fundamental constant variation searches (ΞΌ, Ξ±); (3) Metastable atom and ion trapping β€” developing new trapping methods for precision spectroscopy of exotic species; (4) Pulse and Fourier transform microwave spectroscopy β€” rotational spectroscopy of transient species. Direct applications to molecular quantum sensing and fundamental physics.

Department(s)/lab(s): Physics | Institute of Semiconductor Optics and Functional Interfaces (IHFG) @ Stuttgart
Summary:

Michler's IHFG grows and studies semiconductor quantum dots as on-demand single- and entangled-photon sources, including telecom-band emitters, on-chip Hanbury-Brown-Twiss/photonic integration, and atom-QD hybrid interfaces - core fundamental-light and quantum-photonic-sensing resources. Cleanroom epitaxy on site. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work supplies nonclassical light sources that can enhance optical sensing.
