Investigating Radiation Effects in Quantum Information Technologies
Abstract
This fundamental research program will investigate the effects of radiation on trapped-ion quantum information systems. Trapped atomic ions are a leading candidate for scalable quantum computation, with long coherence times, near-background-free quantum readout, and the highest-reported single- and two-qubit gate fidelities. Yet, it is currently unknown whether these advantageous properties of trapped ion quantum systems will persist when subjected to high-radiation environments. Understanding potential failure mechanisms and vulnerabilities early in the development of such systems will be crucial for mitigating these effects in more sophisticated iterations of quantum devices. The major goals of this project will be to measure the real-time changes in the ion qubit (a) lifetimes, (b) coherence times, (c) single-site rotation fidelities, and (d) entangling gate fidelities when exposed to an array of radiation sources. Such changes, were they to exceed quantifiable thresholds, would severely reduce or entirely destroy the computational advantage of a quantum system. Importantly, our measurements will be sensitive to detrimental radiation effects while the ion-trap quantum computer is in operation, rather than simply testing the trap components offline.
