@article{Cui2021SusceptibilityOT, title={Susceptibility of trapped-ion qubits to low-dose radiation sources}, author={Jiafeng Cui and A. J. Rasmusson and Marissa D’Onofrio and Yu-Xia Xie and Evangeline Wolanski and Philip Richerme}, journal={Journal of Physics B: Atomic, Molecular and Optical Physics}, year={2021}, volume={54} }

We experimentally study the real-time susceptibility of trapped-ion quantum systems to small doses of ionizing radiation. We expose an ion-trap apparatus to a variety of α, β, and γ sources and measure the resulting changes in trapped-ion qubit lifetimes, coherence times, gate fidelities, and motional heating rates. We found no quantifiable degradation of ion trap performance in the presence of low-dose radiation sources for any of the measurements performed. This finding is encouraging for the…

A Systematic Methodology to Compute the Quantum Vulnerability Factors for Quantum Circuits

- Computer ScienceArXiv
- 2021

The Quantum Vulnerability Factor (QVF) is proposed as a metric to measure the impact that the corruption of a qubit has on the circuit output probability distribution, and guidelines on how to map the qubits in the real quantum computer to reduce the output error and to reduced the probability of having a radiation-induced corruption to modify the output.

Impact of ionizing radiation on superconducting qubit coherence

Evidence is provided that ionizing radiation from environmental radioactive materials and cosmic rays contributes to an elevated quasiparticle density, which it is predicted would ultimately limit the coherence times of superconducting qubits of the type measured here to milliseconds.
