CUPID (CUORE Upgrade with Particle ID) is a next-generation tonne-scale experiment that will use arrays of low-temperature calorimeters to search for rare processes like neutrinoless double beta decay. While CUORE (Cryogenic Underground Observatory for Rare Events) has already demonstrated the concept of operating a tonne-scale array at low temperatures (~10 mK), CUPID aims to significantly...

Excess quasiparticles are universally observed to limit coherence times in superconducting qubits. It is hypothesized that natural radiation in the laboratory environment could be the cause. We will review the evidence for excess quasiparticles and explore our hypothesis that environmental radiation is the source of them. Plans for an imminent experiment to test the hypothesis by placing a...

Quantum technology enables new measurements and thus new insights in fundamental physics, applied physics, chemistry, and biology. We will discuss two examples:
Using interference of matter waves, we have recorded the most precise measurement of the fine structure constant, at 0.20-part-per-billion accuracy. Comparison with Penning trap measurements of the electron gyro-magnetic anomaly is...
