Kavli Affiliate: Oskar Painter | First 5 Authors: Guillaume Marcaud, David Perello, Cliff Chen, Esha Umbarkar, Conan Weiland | Summary: The use of $alpha$-tantalum in superconducting circuits has enabled a considerable improvement of the coherence time of transmon qubits. The standard approach to grow $alpha$-tantalum thin films on silicon involves heating the substrate, which takes […]
