Quantum Sensors and Dark Matter Detection

The last two decades have witnessed rapid developments in quantum sensing, enabling precision measurements of time, acceleration and magnetism. These sensors seem well suited to dramatically extend current experimental probes of dark matter. For example, these techniques can search for light dark matter in the mass range 10^(-22) eV - 1 GeV, while also being able to probe certain kinds of ultra-heavy dark matter in the mass range 10^(18) GeV - 10^(33) GeV. This broad search for dark matter, well beyond the well explored WIMP paradigm, is necessary since observational constraints on the mass of dark matter allow it to lie anywhere between 10^(-22) eV - 10^(48) GeV, with a number of theoretically well motivated candidates spanning this vast range. In this talk, I will discuss these experimental methods and highlight recent experimental progress in their implementation. In addition, I will also touch on their potential application to direct laboratory searches of dark energy.
