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…

Materials loss measurements using superconducting microwave resonators

Corey Rae Harrington McRae, Haozhi Wang, Jiansong Gao +5

The performance of superconducting circuits for quantum computing is limited by materials losses. In particular, coherence times are typically bounded by two-level system (TLS) los…

Thin film metrology and microwave loss characterization of indium and aluminum/indium superconducting planar resonators

C. R. H. McRae, J. H. Béjanin, C. T. Earnest +6

Scalable architectures characterized by quantum bits (qubits) with low error rates are essential to the development of a practical quantum computer. In the superconducting quantum…

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…
