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…
Using a 4-megapixel hybrid photon counting detector for fast, lab-based nanoscale x-ray tomography
Jordan Fonseca, Zachary H. Levine, Joseph W. Fowler +8
Hybrid photon counting detectors (HPCDs) have unlocked new capabilities for x-ray-based measurements at synchrotrons around the world in the last 30 years. By leveraging independen…
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…
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…
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…
