| Summary:
We point out that power measurements of single quasiparticle devices open a
new avenue to detect dark matter (DM). The threshold of these devices is set by
the Cooper pair binding energy, and is therefore so low that they can detect DM
as light as about an MeV incoming from the Galactic halo, as well as the
low-velocity thermalized DM component potentially present in the Earth. Using
existing power measurements with these new devices, as well as power
measurements with SuperCDMS-CPD, we set new constraints on the spin-independent
DM scattering cross section for DM masses from about 10 MeV to 10 GeV. We
outline future directions to improve sensitivity to both halo DM and a
thermalized DM population in the Earth using power deposition in quantum
devices.
