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...

Construction of models of temperature dependent variations in the heights of permanently operating IGS stations

Abstract Based on a study of the behavior of several permanently operated stations of the IGS network, the impact of ambient temperature on the heights of these stations is tested and assessed. The studies used relative GNSS determinations of very short baselines, which have very...
