Superconducting quantum bits (qubits) are sensitive to ionizing radiation, including γ-rays from environmental radioactivity and cosmic-ray muons. These interactions produce quasiparticle bursts in the substrate, causing decoherence and correlated errors across multiple qubits—posing a critical challenge for fault-tolerant quantum computing. While passive shielding can suppress most...
