Impact of embedded Ho on the performance of the transition-edge sensor microcalorimeters of the HOLMES experiment
Douglas Bennett, Matteo Borghesi, Pietro Campana +19
We present a detailed investigation of the performance of transition-edge sensor (TES) microcalorimeters with Ho atoms embedded by ion implantation, as part of the HOLMES e…

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…
