Founding Director Chicago Quantum Exchange. Joint Senior Scientist Argonne. Large infrastructure-rich group with strong industry ties (IBM, Intel, Google quantum).
Primary focus: immune engineering for vaccines and cancer immunotherapy. Quantum sensing relevance: co-authored 2025 fluorescent-protein spin qubit paper (Physics World Top-10) with Maurer and Awschalom, contributing protein engineering expertise to develop biological alternatives to NV centers. Collaborates on quantum biosensors for real-time monitoring of immune cell activity (Chan Zuckerberg Biohub). Primarily a collaboration gateway for NV biosensing rather than standalone quantum sensing PI.

Hemmer pioneered NV-diamond spin sensing and super-resolution with spin defects, working on coherent control, photonic integration of NV sensors, and diamond-based magnetometry/imaging bridging physics and engineering. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is directly in the NV ensemble sensing lineage, emphasizing photonic integration and super-resolution readout.
Hoogenboom leads a biophysics group at UCL specializing in high-speed atomic force microscopy. Research directions: (1) High-speed AFM — imaging conformational dynamics of DNA, proteins (including membrane channels), and chromatin at ms time resolution and sub-nm spatial resolution in aqueous conditions; (2) Nuclear pore complex — mapping transport selectivity and structure of NPCs in native nuclear envelopes using AFM; (3) Antimicrobial mechanisms — imaging membrane disruption by antimicrobial peptides in real time; (4) AFM-based force spectroscopy — measuring single-molecule interaction forces in chromatin and protein assemblies. Strong relevance to biological sensing at the single-molecule level.
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.
Krueger's chemistry group develops diamond and nanodiamond surface chemistry, functionalization and bioconjugation that make NV centres viable, shallow, coherent quantum sensors for chemical and biological targets - the materials-chemistry enabler for NV ensemble sensing. She co-leads Stuttgart's quantum-technologies profile. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is enabled at the surface-chemistry level by this work.

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.
Prawer is the founding figure of Melbourne diamond science, spanning colour-centre quantum technology, diamond surface chemistry and — unusually — clinical translation. His group developed the nitrogen-doped ultrananocrystalline diamond electrode arrays used in the Australian diamond bionic eye, a hermetically sealed, chronically implantable retinal stimulator that has been through human implantation; that is a rare example of an exotic-materials sensing/stimulation technology carried into human trials. In parallel the group works on diamond surface termination and functionalisation for near-surface NV sensing, nanodiamond bioconjugation, and diamond as a radiation-hard detector material. 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 surface- and materials-engineering work is precisely what sets the standoff distance, and hence the achievable pT/sqrt(Hz) sensitivity, of near-surface NV ensembles used for DEER and nanoscale NMR. Preferred attribute present: demonstrated human trials with a complex implanted technology.
Treussart uses fluorescent nanodiamonds (NV centres) as photostable bio-probes: intracellular single-particle tracking, nanoscale thermometry/magnetometry, and multimodal biosensing in cells and organisms, alongside super-resolution imaging - a direct NV-ensemble-to-biology bridge. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is applied here to living cells via nanodiamond probes.
