Distinguishing types of correlated errors in superconducting qubits
Hannah P. Binney, H. Douglas Pinckney, Kate Azar +15
Errors in superconducting qubits that are correlated in time and space can pose problems for quantum error correction codes. Radiation from cosmic and terrestrial sources can incre…
Measuring quasiparticle dynamics for particle impact reconstruction in a superconducting qubit chip
E. Celi, R. Linehan, P. M. Harrington +7
Quasiparticle poisoning following particle impacts poses a significant challenge to the development of fault-tolerant superconducting quantum computers, as a sudden excess of quasi…
Characterization of Radiation-Induced Errors in Superconducting Qubits Protected with Various Gap-Engineering Strategies
H. Douglas Pinckney, Thomas McJunkin, Alan W. Hunt +26
Impacts from high-energy particles cause correlated errors in superconducting qubits by increasing the quasiparticle density in the vicinity of the Josephson junctions (JJs). Such…
Synchronous Detection of Cosmic Rays and Correlated Errors in Superconducting Qubit Arrays
Patrick M. Harrington, Mingyu Li, Max Hays +13
Quantum information processing at scale will require sufficiently stable and long-lived qubits, likely enabled by error-correction codes. Several recent superconducting-qubit exper…
