Grain size in low loss superconducting Ta thin films on c-axis sapphire
Sarah Garcia Jones, Nicholas Materise, Ka Wun Leung +6
In recent years, the implementation of thin-film Ta has led to improved coherence times in superconducting circuits. Efforts to further optimize this materials set have become a fo…
Disentangling the sources of ionizing radiation in superconducting qubits
L. Cardani, I. Colantoni, A. Cruciani +27
Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. In this work, we mea…
Mitigating coherent leakage of superconducting qubits in a large-scale quantum socket
T. G. McConkey, J. H. Béjanin, C. T. Earnest +4
A practical quantum computer requires quantum bit (qubit) operations with low error rates in extensible architectures. We study a packaging method that makes it possible to address…
