X-ray magnetic circular dichroism and resonant inelastic X-ray scattering explained: role of many-body correlation and valence fluctuations
Beom Hyun Kim, Sang-Jun Lee, H. Huang +12
X-ray magnetic circular dichroism (XMCD) and resonant inelastic X-ray scattering with magnetic circular dichroism (RIXS-MCD) provide unparalleled insights into the electronic and m…
Computed models of natural radiation backgrounds in qubits and superconducting detectors
Joseph Fowler, Ian Fogarty Florang, Nathan Nakamura +3
Naturally occurring radiation backgrounds cause correlated decoherence events in superconducting qubits. These backgrounds include both gamma rays produced by terrestrial radioisot…
Primary activity measurement of an Am-241 solution using microgram inkjet gravimetry and decay energy spectrometry
Ryan P. Fitzgerald, Bradley Alpert, Denis E. Bergeron +11
We demonstrate a method for radionuclide assay that is spectroscopic with 100 % counting efficiency for alpha decay. Advancing both cryogenic decay energy spectrometry (DES) and dr…
Direct Imaging of Transition-Edge Sensors with Scanning SQUID Microscopy
Samantha Walker, Austin Kaczmarek, Jason Austermann +10
Significant advancements have been made in understanding the physics of transition-edge sensors (TESs) over the past decade. However, key questions remain, particularly a detailed…
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…
