Materials loss measurements using superconducting microwave resonators

Author(s)
Corey Rae H. McRae, Haozhi Wang, Jiansong Gao, Michael R. Vissers, Teresa Brecht, A Dunsworth, David P. Pappas, J. Mutus
The performance of superconducting circuits for quantum computing is limited by materials losses. In particular, coherence times are typically bounded by two
