Quantum Sensors for High Energy Physics

Quantum sensors are finding use in various HEP applications where they enable searches for new, weakly-coupled physics in regimes that cannot be otherwise probed.  In this talk, I will survey the new quantum techniques being developed for matter searches and gravitational wave detection with a particular focus on superconducting qubits as single photon/phonon detectors.  In this context, a quantum computer is automatically a dark matter detector in the same way that a classical silicon transistor computer is also a cosmic ray detector.
