講演概要
Developments over the last decade have pushed the search for particle dark matter to new frontiers, from just below the proton mass down to the keV-scale lower mass limit for thermally-produced dark matter. Galactic DM at this mass is kinematically matched with the energy needed to break a Cooper pair in common superconductors (~meV). Quantum sensors such as superconducting qubits are sensitive to these broken Cooper pairs, and can potentially be exploited as low-threshold detectors for particle-like DM scattering. On the other hand, excitations that break Cooper pairs in qubits can lead to lower T1 times and catastrophic correlated errors in a Quantum Computer. The coupling between excitations in qubit substrates and qubit performance lies at the intersection of quantum sensing and quantum computing. In this talk I will overview the research program being conducted by the Quantum Science Center group at Fermilab as part of a broad effort in quantum sensing and computing, focusing on the interaction of qubits with their environment.
