Summary:

Degen leads the Spin Physics and Imaging group, one of the world's leading NV-center magnetometry labs. Research directions (as of 2025): (1) Scanning NV magnetometry of quantum materials β€” NV-tipped cantilevers image current flow (≲50 nm resolution) in graphene heterostructures and resolve domain walls in antiferromagnets/ferroelectrics; cryogenic scanning down to 350 mK in dilution refrigerator (published Appl.

Department(s)/lab(s): Physics (LKB) | Optomechanics and Quantum Measurements Team @ ENS Paris
Summary:

Deleglise works on cavity optomechanics and microwave-to-optical photon transduction, aiming to coherently interconnect superconducting-circuit and optical-photon quantum-network nodes; he is also affiliated with LPENS' Quantic team on circuit-QED and bosonic-code quantum error correction.

Department(s)/lab(s): Physics | DeMille Group @ UChicago
Summary:

Experimental AMO physicist focused on precision measurement for fundamental physics. Primary directions: (1) ACME experiment measuring electron electric dipole moment to unprecedented precision using ThO molecular beam β€” tests for new CP-violating physics beyond the Standard Model; (2) ultracold polar molecule quantum simulation and quantum information in optical tweezers. Atomic coherence techniques underpin SERF/OPM magnetometry. Joined UChicago from Yale 2022.

Department(s)/lab(s): Institute of Physics (KOMET) | AG Demsar - Ultrafast Quantum Materials @ JGU
Summary:

Demsar's group studies non-equilibrium dynamics in quantum materials with ultrafast optical and terahertz probes: THz time-domain spectroscopy, optical pump-probe and time-resolved photoemission applied to superconductors, charge-density-wave systems and magnetic materials, including light-induced phase transitions and the dynamics of collective modes. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is a borderline inclusion -- it is not quantum sensing per se -- but it is kept because the group's core competence is pushing temporal resolution (fs) and coherent THz detection to their limits, which is a legitimate adjacent skill set and a plausible pivot for someone with lock-in/pulsed-measurement expertise.

Department(s)/lab(s): Physics – QOLS / Centre for Cold Matter | Centre for Cold Matter – Quantum Technology & Dark Matter (Devlin) @ Imperial
Summary:

Devlin is a Royal Society URF at the Centre for Cold Matter building a new experiment to detect axion and dark matter particles. His prior work at CERN's BASE collaboration (Penning trap antiproton experiment) used the ultra-sensitive superconducting detection circuit of a cryogenic Penning trap to set new constraints on axion-like particle couplings to photons (~2.79 neV/cΒ² range; PRL 2021). At Imperial he is developing a Penning trap single-photon counter concept using a single trapped electron to detect 30–60 GHz photons from axion-photon conversion in a strong magnetic field (arXiv 2601.05472, March 2026), targeting axion masses of 124–248 ΞΌeV. This approach could overcome the standard quantum noise limit that hampers conventional haloscope searches at high mass. Active PDRA posting open May 2025.

Department(s)/lab(s): Electrical, Computer & Energy Engineering | Frequency Combs & Quantum Metrology Group @ CUBoulder
Summary:

Diddams' group develops optical frequency combs (fiber, microresonator, and mid-IR) and applies them to quantum metrology, optical clocks, precision spectroscopy from UV to THz, low-noise microwave photonics, and astronomical spectrograph calibration; he directs CU's Quantum Engineering Initiative. 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): Applied Physics | Digonnet Group (Ginzton Laboratory) @ Stanford
Summary:

Digonnet's group develops high-sensitivity fiber-optic sensors, especially resonant and interferometric fiber-optic gyroscopes engineered to approach fundamental (shot-noise/quantum) rotation-sensing limits, alongside specialty fiber lasers and amplifiers.

Department(s)/lab(s): School of Physics | Quantum Theory Group @ USyd
Summary:

Doherty is a theorist whose early work established much of the modern framework for continuous quantum measurement and quantum feedback control, and who now works across quantum information theory, error correction and the characterisation of quantum devices. For a sensing candidate the relevant body of work is the measurement/feedback theory: conditional evolution under continuous observation, the role of back-action, and the design of feedback protocols that stabilise a quantum system while extracting information from it. 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€” the continuous-measurement formalism he helped build is what one uses to ask whether a pT/sqrt(Hz) NV ensemble measurement is saturating its quantum Fisher information bound or merely its shot-noise bound. Borderline inclusion β€” the current group output is largely quantum computing theory rather than sensing β€” but retained under the inclusive rubric given the measurement-theory pedigree.

Summary:

Dotsenko is a permanent member of LKB's Rydberg-atom cavity-QED team (successor to Haroche/Brune's circular-Rydberg-atom programme), using long-lived circular Rydberg states strongly coupled to microwave photons in high-Q cavities for quantum non-demolition measurement, entanglement generation, and microwave-photon-number quantum sensing.
