IQUIST Seminar: Noah Kurinsky, SLAC

Over the last few decades, searches for dark matter above the proton mass have advanced significantly across direct and indirect searches, and recent efforts to detect low-mass axions have accelerated. In contrast, searches for dark matter at meV energy scales (encompassing high-mass axions and sub-GeV particle dark matter) have until recently been comparatively unprobed. In this talk, I will discuss the state of meV-scale sensing for the direct detection field, and prospects for applying quantum measurement techniques, including sensors derived from superconducting qubits, to lowering energy thresholds to the single quasiparticle limit over the next decade. I will also discuss calibration challenges that face the community and common problems that will need to be solved to accurately probe this new regime.
