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…

Full characterization of measurement-induced transitions of a superconducting qubit
Thomas Connolly, Pavel D. Kurilovich, Vladislav D. Kurilovich +12
Repeated quantum non-demolition measurement is a cornerstone of quantum error correction protocols. In superconducting qubits, the speed of dispersive state readout can be enhanced…

High-frequency readout free from transmon multi-excitation resonances
Pavel D. Kurilovich, Thomas Connolly, Charlotte G. L. Bøttcher +12
Quantum computation will rely on quantum error correction to counteract decoherence. Successfully implementing an error correction protocol requires the fidelity of qubit operation…
