Recovery dynamics of a gap-engineered transmon after a quasiparticle burst
Heekun Nho, Thomas Connolly, Pavel D. Kurilovich +4
Ionizing radiation impacts create bursts of quasiparticle density in superconducting qubits. These bursts temporarily degrade qubit coherence which can be detrimental for quantum e…

Quasiparticle-induced decoherence of a driven superconducting qubit
Mykola Kishmar, Pavel D. Kurilovich, Andrey Klots +3
We develop a theory for two quasiparticle-induced decoherence mechanisms of a driven superconducting qubit. In the first mechanism, an existing quasiparticle (QP) tunnels across th…
