Ultrastrong Coupling and Coherent Dynamics in a Gate-Tunable Transmon Qubit
I. Casal Iglesias, F. J. Matute-Cañadas, G. O. Steffensen +10
Ultrastrong light-matter coupling (USC) gives access to exotic quantum phenomena and promises faster quantum gates, yet coherent time-domain control in this regime remains largely…

Anomalous metallic phase and reduced critical current in superconducting nanowires due to inverse proximity effect
G. M. Oliveira, G. O. Steffensen, I. Casal Iglesias +7
Superconductor-to-metal transitions (SMTs) are key probes of mesoscopic superconductivity, but their interpretation can be complicated by device geometry and measurement conditions…
