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… Expand
A Systematic Methodology to Compute the Quantum Vulnerability Factors for Quantum Circuits
TLDR
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.

Demonstration of the trapped-ion quantum CCD computer architecture.
TLDR
A cryogenic surface trap is used to integrate all necessary elements of the QCCD architecture-a scalable trap design, parallel interaction zones and fast ion transport-into a programmable trapped-ion quantum computer that has a system performance consistent with the low error rates achieved in the individual ion crystals.

Single ion qubit with estimated coherence time exceeding one hour
TLDR
After properly suppressing magnetic-field fluctuations, frequency instability and leakage of the microwave reference-oscillator, the authors infer coherence times of 5500 s for an Yb ion qubit, which will accelerate practical applications of quantum memories for various quantum information processing.

Impact of ionizing radiation on superconducting qubit coherence
TLDR
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. Expand
