Oxygen Vacancies in Niobium Pentoxide as a Source of Two-Level System Losses in Superconducting Niobium
Daniel Bafia, Akshay Murthy, Anna Grassellino +1
We identify a major source of quantum decoherence in three-dimensional superconducting radio-frequency (SRF) resonators and two-dimensional transmon qubits composed of oxidized nio…
Discovery of Nb hydride precipitates in superconducting qubits
Jaeyel Lee, Zuhawn Sung, Akshay A. Murthy +3
We report the first evidence of the formation of niobium hydrides within niobium films on silicon substrates in superconducting qubits fabricated at Rigetti Computing. We combine c…
Signatures of Enhanced Superconducting Properties in Niobium Cavities
D. Bafia, A. Grassellino, M. Checchin +2
Superconducting radio-frequency (SRF) niobium cavities are critical for modern particle accelerators, as well as for advancing superconducting quantum systems and enabling ultra-se…
