Microwave cavity-based dark matter axion searches are presented with two challenges to achieving credible discovery potential. The first, common to searches at all axion masses, is achieving the requisite sensitivity, which has been a driver for quantum sensing. The HAYSTAC experiment has been a leader in the development of superconducting devices for the post-inflation axion, including the...

The Superconducting Quasiparticle-Amplifying Transmon (SQUAT) is a sensor architecture for meV (THz) detection based on a weakly charge-sensitive transmon qubit directly coupled to a transmission line. Energy depositions in the qubit capacitor generate quasiparticles that tunnel across the Josephson junction. Each tunnel changes the qubit parity and produces a measurable signal in CW...

Ultralight bosonic dark matter candidates, such as axions, axion-like particles, and dark photons, can behave as classical coherent fields oscillating at frequencies set by the particle mass. In the microwave regime, this motivates detection strategies based on superconducting quantum devices, where near-quantum-limited amplification and single-excitation sensitivity can probe extremely weak...

The SQMS Center develops state-of-the-art superconducting technologies for ultra-sensitive searches for physics beyond the Standard Model. Central to this effort are superconducting cavities with world-record quality factors, operating as precision sensors for extremely weak signals. When integrated with superconducting devices, these systems can enable even further enhanced sensitivity and...
