Population-Based Discrimination of Classical and Few-Photon Microwave Fields with a Flux-Tunable Transmon Qudit

Interactions between few-photon microwave fields and superconducting artificial atoms provide a method to study photon statistics and manipulate quantum states for photonic quantum information processing. Superconducting transmons couple to microwave fields through an anharmonic...

Frequency control of superconducting resonators using integrated interferometers

Predictable frequency trimming of superconducting resonators at liquid-helium temperatures requires a tuning element whose usable range remains well defined despite screening currents and hysteresis. Here, we realize flux-controlled λ/4 coplanar-waveguide resonators terminated by...
