Qubits as low-energy sensors, from axions to neutrinos

Superconducting qubits are incredibly sensitive to their environment, which give them great promise as sensors.  The superconducting quasiparticle-amplifying transmon (SQUAT) re-optimizes the classic qubit architecture to maximize sensitivity to THz (meV) signals.  Tiny energy depositions in the qubit islands break Cooper pairs to generate quasiparticles, which can be detected as they tunnel across the qubit junction as a shift in the qubit parity state.  These devices promise several beneficial features, including excellent energy sensitivity and multiplexability.  Here I will present the first measurements of SQUAT devices as well as discuss future work and potential applications of this new sensor, from axion dark matter to coherent elastic neutrino-nucleus scattering.
