Evidence for a low-gap component in compressively stressed niobium thin films
J. T. Paustian, Maciej Olszewski, Kiichi Okubo +6
We investigate the microwave response of sputtered Nb films as a function of biaxial film stress. Although transport measurements show nearly identical superconducting transition t…
Quasiparticle-induced transitions in a fluxonium qubit
Maksim Litskevich, Kesavan Manivannan, Benjamin Byrd +4
Quasiparticles are a prominent decoherence source in superconducting qubits, but their effects are notoriously difficult to isolate in fluxonium. Unlike the transmon, fluxonium is…
Low-loss Nb on Si superconducting resonators from a dual-use spintronics deposition chamber and with acid-free post-processing
Maciej W. Olszewski, Jadrien T. Paustian, Tathagata Banerjee +13
Magnetic impurities are known to degrade superconductivity. For this reason, physical vapor deposition chambers that have previously been used for magnetic materials have generally…
Modeling phonon-mediated quasiparticle poisoning in superconducting qubit arrays
Eric Yelton, Clayton P. Larson, Vito Iaia +8
Correlated errors caused by ionizing radiation impacting superconducting qubit chips are problematic for quantum error correction. Such impacts generate quasiparticle (QP) excitati…
Measurement-induced state transitions in dispersive qubit readout schemes
Konstantin N. Nesterov, Ivan V. Pechenezhskiy
The dispersive-readout scheme enables quantum nondemolition measurement of superconducting qubits. An increased readout power can shorten the readout time and reduce the state disc…
Counting statistics of microwave photons in circuit QED
Konstantin N. Nesterov, Ivan V. Pechenezhskiy, Maxim G. Vavilov
In superconducting circuit architectures for quantum computing, microwave resonators are often used both to isolate qubits from the electromagnetic environment and to facilitate qu…
