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.

Best known as a collider (ATLAS) physicist, Miller also leads the BREAD collaboration's broadband dish-antenna search for axion dark matter, converting axions to photons inside a solenoid magnet and reading them out with a THz receiver and Fourier-transform spectrometer to cover mass ranges inaccessible to narrowband cavity haloscopes. This is a fundamentally different quantum-sensing strategy than solid-state NV-ensemble magnetometers/thermometers, which reach pT/sqrt(Hz)-class sensitivity via DEER, NMR, and T1-relaxometry protocols on spin ensembles; Miller's approach instead pushes broadband photon-counting sensitivity for fundamental-physics searches.
