Knappe develops microfabricated chip-scale atomic magnetometers and clocks and applies them to biomagnetism (MEG/MCG) and NMR; she co-founded FieldLine to commercialise OPM sensors. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
Knirck builds novel microwave- and mm-wave-frequency detectors (ADMX resonant cavities, MADMAX dielectric haloscopes, and the broadband BREAD/dish-antenna concept) to search for axion dark matter, explicitly leveraging cutting-edge single-photon quantum sensing to push beyond the standard quantum limit. He describes axion searches as sitting directly at the intersection of particle physics, astrophysics, photonics, and quantum sensing, and is building a new experimental group at Harvard.
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.
Kocharovskaya is a theorist (with supporting experiment) in coherent optics: EIT, lasing without inversion, and X-ray/gamma quantum optics using nuclear coherent control (Moessbauer nuclei) for ultra-narrowband photon storage and precision spectroscopy. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides coherent-control primitives relevant to precision sensing.
Gijsje Koenderink (Full Professor, BioNanoscience) investigates active and passive mechanics of the cytoskeleton. Research: (1) active matter — motor-filament composite networks generating spontaneous mechanical activity; (2) cell mechanics — cytoskeletal contributions to cell shape, migration, and division; (3) biomaterials — designing synthetic cytoskeletal analogues; (4) optical tweezers and AFM rheology of reconstituted networks. Spinoza Prize 2021. ERC Advanced Grant.
Kolkowitz's group builds ultra-precise strontium optical lattice clocks for differential clock comparisons and fundamental-physics tests, and separately pioneered scanning single-NV magnetometry for imaging nanoscale current and spin transport in quantum materials. This combination of atomic-clock and solid-state defect-spin sensing places the group's diamond work squarely alongside the broader NV ensemble sensing literature (DEER, nanoscale NMR, T1 relaxometry) that has achieved pT/sqrt(Hz)-class field sensitivities; the lab is actively recruiting postdocs in both directions.
Kolthammer works on quantum photonics with an emphasis on nonclassical states of light and their applications to quantum information and sensing. Research highlights: (1) Gaussian Boson Sampling — first time-bin encoded GBS experiment using a loop-based interferometer with superconducting TES photon-number-resolving detectors, demonstrated enhancement in dense-subgraph search over classical methods (PRX 2022); (2) Squeezed state characterisation — nonclassicality certification using multiplexing layouts with superconducting TES detectors, sub-Poisson and sub-binomial statistics (PRA 2017); (3) Frequency-multiplexed photon pair sources — electro-optic frequency shifting for indistinguishable single-photon multiplexing without added multi-photon events; (4) Photonic quantum sensing — developing time-bin encoded platforms for quantum-enhanced sensing and quantum advantage demonstrations.
Koerber develops ultra-low-noise multichannel SQUID magnetometers and ultra-low-field NMR/MRI and biomagnetism instrumentation in PTB's shielded rooms. The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.
Kornack (from Romalis's Princeton group) founded Twinleaf, which builds atomic magnetometers, alkali-noble-gas SERF comagnetometers and low-noise magnetic shielding/coils used across fundamental-physics and sensing experiments. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
Kovac leads the BICEP/Keck CMB-polarization program at the South Pole, designing and deploying multiple generations of radio telescopes and cryogenic detector arrays (TES bolometers with SQUID-multiplexed readout) to search for the inflationary gravitational-wave signature in the cosmic microwave background. This is an astronomy pivot squarely enabled by quantum-limited cryogenic detector technology, matching the CMB-instrumentation branch of the quantum-sensing tree.
