Assessing the Sensitivity of Niobium- and Tantalum-Based Superconducting Qubits to Infrared Radiation
Michael Kerschbaum, Felix Wagner, UroÅ¡ OgnjanoviÄ +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…
