Kinetic inductance current sensor for visible to near-infrared wavelength transition-edge sensor readout
Paul Szypryt, Douglas A. Bennett, Ian Fogarty Florang +12
Single-photon detectors based on the superconducting transition-edge sensor are used in a number of visible to near-infrared applications, particularly for photon-number-resolving…

Spectroscopic measurements and models of energy deposition in the substrate of quantum circuits by natural ionizing radiation
Joseph W. Fowler, Paul Szypryt, Raymond Bunker +16
Naturally occurring background radiation is a source of correlated decoherence events in superconducting qubits that will challenge error-correction schemes. To characterize the ra…

Few-electron highly charged muonic Ar atoms verified by electronic x rays
T. Okumura, T. Azuma, D. A. Bennett +40
Electronic x rays emitted by muonic Ar atoms in the gas phase were observed using a superconducting transition-edge-sensor microcalorimeter. The high-precision energy spectra p…
