Correlated quasiparticle poisoning from phonon-only events in superconducting qubits
E. Yelton, C. P. Larson, K. Dodge +2
Throughout multiple cooldowns we observe a power-law reduction in time for the rate of multi-qubit correlated poisoning events, while the rate of shifts in qubit offset-charge rema…
Quasiparticle poisoning of superconducting qubits with active gamma irradiation
C. P. Larson, E. Yelton, K. Dodge +5
When a high-energy particle, such as a -ray or muon, impacts the substrate of a superconducting qubit chip, large numbers of electron-hole pairs and phonons are created. The ens…
Synthetic high angular momentum spin dynamics in a microwave oscillator
Saswata Roy, Alen Senanian, Christopher S. Wang +10
Spins and oscillators are foundational to much of physics and applied sciences. For quantum information, a spin 1/2 exemplifies the most basic unit, a qubit. High angular momentum…
Modeling phonon-mediated quasiparticle poisoning in superconducting qubit arrays
Eric Yelton, Clayton P. Larson, Vito Iaia +8
Correlated errors caused by ionizing radiation impacting superconducting qubit chips are problematic for quantum error correction. Such impacts generate quasiparticle (QP) excitati…
Phonon downconversion to suppress correlated errors in superconducting qubits
V. Iaia, J. Ku, A. Ballard +6
Quantum error correction can preserve quantum information in the presence of local errors, but correlated errors are fatal. For superconducting qubits, high-energy particle impacts…
