Novel Quantum Sensors for Light Dark Matter and Neutrino Detection

Abstract

The fields of light dark matter and neutrino physics offer compelling signals at recoil energies of eV to even meV, well below the [Formula: see text] keV thresholds of many techniques currently employed in these fields. Sensing of such small energies can benefit from the emergence of so-called quantum sensors, which employ fundamentally quantum mechanical phenomena to transduce energy depositions into electrical signals. This review focuses on quantum sensors under development that will enhance and extend the search for “particle-like” interactions of dark matter or enable new measurements of neutrino properties in the coming years.
