Talk

In recent years, European laboratories have provided numerous insights into the effects of radioactivity on quantum circuits. Superconducting resonators, fluxonium qubits, and transmon qubits have been operated in deep underground facilities and exposed to radioactive sources. In this contribution, I will discuss the results and future perspectives.

Ionizing radiation has been shown to reduce the performance of superconducting quantum circuits. In this report, we evaluate the expected contributions of different sources of ambient radioactivity for typical superconducting qubit experiment platforms. Our assessment of radioactivity inside a typical cryostat highlights the importance of selecting appropriate materials for the experiment...
