Radiation Impact on Superconducting Qubits (RISQ 2024)
One West
Wilson Hall
This is the first iteration of a new workshop series on the subject of Radiation Impact on Superconducting Qubits (RISQ) that will bring together the broader QIS and particle physics communities to assess the effects of radiation and cosmic rays on superconducting solid-state qubits, and development of the tools needed to address the problem. The workshop will take place at Fermi National Accelerator Laboratory on May 30-31, 2024 and will feature two days of invited talks, detailed discussions, and tours of dedicated lab facilities for addressing these issues. Tours will be allocated on a first-come, first-served basis, so please register as soon as possible and indicate that you would like a tour if interested. For those who do not attend tours, space will be provided for working discussions.
On May 29, 2024, a related satellite workshop will be held on the subject of GEANT4/G4CMP development for the modeling of energy dissipation in solid-state systems. The registration form includes a question as to whether you intend to come to this satellite workshop day, but separate registration will be required (instructions to be circulated at a later date).
Alongside this workshop, we will hold a ribbon cutting for the Quantum Underground Instrumentation Experimental Testbed (QUIET), the newly-commissioned QSC underground QIS facility at Fermilab. The exact time of this ribbon cutting has not been decided.
There is no registration fee for this workshop. Talks will be invite-only. Abstracts can be submitted to present a poster at the reception.

Muon tagging using Kinetic Inductance Detectors
Ionizing radiation, particularly environmental radioactivity and cosmic-ray muons, pose significant challenges to the coherence and reliability of superconducting quantum processors. In this talk, I will introduce a novel approach to mitigate the detrimental effects of atmospheric muons on arrays of superconducting qubits. Our strategy involves equipping a superconducting quantum processor with an active muon veto system designed to tag and veto operations following a muon interaction within the chip. I will outline the concept, design, and technology behind the muon veto detector, with a focus on achieving high detection efficiency and negligible dead-time. Leveraging insights from Particle Physics experiments and the INFN CALDER project, we propose a cryogenic muon veto based on Kinetic Inductance Detectors (KIDs) technology, tightly integrated with the superconducting quantum chip. Results from Monte Carlo simulations and a preliminary design of the muon veto will be presented. By demonstrating the effectiveness of this strategy, we aim to significantly reduce correlated errors, enhancing both coherence and frequency stability of superconducting qubits. We plan to test our prototype using a high-performing quantum chip provided by the Superconducting Quantum Materials and Systems (SQMS) Center, with the objective of validating its performance and applicability in practical quantum computing scenarios.
