Summary

Story summary

Radiation from cosmic and terrestrial sources disrupts superconducting qubits, causing correlated errors and reduced coherence.
Recent research attributes about 17% of superconducting processor errors to cosmic rays.
Ionising radiation causes multiqubit anomalies and higher chip-scale failures; mitigation via semiconductor gap engineering and phonon trapping.
A synchronous-detection study links cosmic rays to qubit instability, validating prior models and supporting radiation-hardened designs.
