Description
The interaction between superconducting qubits and quasiparticles that tunnel across the Josephson junction can be used to detect quasiparticle-generating particle scattering events, making them promising platforms for sub-eV phonon/photon sensing. Each tunneling event can flip the qubit charge parity and may also result in energy transfer between the qubit and the quasiparticle. We present a comparative study of the sensitivities of various sensor materials (Al and Hf) and energy sensing methods that detect energy depositions by monitoring the quasiparticle tunneling rate.
