Investigations of Nuclear Interactions in Superconducting Quantum Devices

Superconducting quantum devices (SQDs) are at the forefront of technologies to investigate phenomena such as dark matter and application spaces such as quantum computing. The performance of SQDs is affected by correlated events that occur within the device. These correlated events are, in large part, produced by radiation. Many experimental and simulation studies are underway to understand how naturally occurring radiation and cosmic radiation affect the SQDs. Due to the sensitive nature of the SQDs, small energy changes within the device can have a large effect on output signals. One of our studies is to investigate how nuclear interactions play a role. Nuclear recoil energies are usually out of range of typical nuclear physics experiments. SQDs provides an opportunity to look at nuclear processes in a unique way. We will present results from Geant4 simulations using G4CMP. In this presentation, we will also discuss our experimental setup and outlook.
