Assessing the Sensitivity of Niobium- and Tantalum-Based Superconducting Qubits to Infrared Radiation
Michael Kerschbaum, Felix Wagner, Uroš Ognjanović +7
The use of tantalum films for superconducting qubits has recently extended qubit coherence times significantly, primarily due to reduced dielectric losses at the metal-air interfac…

Imaging of Gate-Controlled Suppression of Superconductivity via the Meissner Effect
P. J. Scheidegger, K. J. Knapp, U. Ognjanovic +5
It was recently discovered that supercurrents flowing through thin superconducting nanowires can be quenched by a gate voltage. This gate control of supercurrents, known as the GCS…
