Evaluating radiation impact on transmon qubits in above and underground facilities
Francesco De Dominicis, Tanay Roy, Ambra Mariani +20
Superconducting qubits can be sensitive to abrupt energy deposits caused by cosmic rays and ambient radioactivity. While previous studies have explored correlated effects in time a…
Disentangling the sources of ionizing radiation in superconducting qubits
L. Cardani, I. Colantoni, A. Cruciani +27
Radioactivity was recently discovered as a source of decoherence and correlated errors for the real-world implementation of superconducting quantum processors. In this work, we mea…
Operating in a deep underground facility improves the locking of gradiometric fluxonium qubits at the sweet spots
Daria Gusenkova, Francesco Valenti, Martin Spiecker +14
We demonstrate flux-bias locking and operation of a gradiometric fluxonium artificial atom using two symmetric granular aluminum (grAl) loops to implement the superinductor. The gr…
Correlated Charge Noise and Relaxation Errors in Superconducting Qubits
C. D. Wilen, S. Abdullah, N. A. Kurinsky +11
The central challenge in building a quantum computer is error correction. Unlike classical bits, which are susceptible to only one type of error, quantum bits ("qubits") are suscep…
