Non-equilibrium Dynamics of Two-level Systems directly after Cryogenic Alternating Bias
V. Iaia, E. S. Joseph, S. Im +10
Two-level systems (TLSs) are tunneling states commonly found in amorphous materials that electrically couple to qubits, resonators, and vibrational modes in materials, leading to e…
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…
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…
Single Flux Quantum-Based Digital Control of Superconducting Qubits in a Multi-Chip Module
Chuan-Hong Liu, Andrew Ballard, David Olaya +15
The single flux quantum (SFQ) digital superconducting logic family has been proposed for the scalable control of next-generation superconducting qubit arrays. In the initial implem…
Quasiparticle Poisoning of Superconducting Qubits from Resonant Absorption of Pair-breaking Photons
Chuan-Hong Liu, David C. Harrison, Shravan Patel +8
The ideal superconductor provides a pristine environment for the delicate states of a quantum computer: because there is an energy gap to excitations, there are no spurious modes w…
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…
Superfluid Onset and Compressibility of He Films Adsorbed on Carbon Nanotubes
Emin Menachekanian, Vito Iaia, Mingyu Fan +7
Third sound measurements of superfluid He thin films adsorbed on 10 nm diameter multiwall carbon nanotubes are used to probe the superfluid onset temperature as a function of t…
Third sound measurements of superfluid He films on multiwall carbon nanotubes below 1K
Emin Menachekanian, John B. S. Abraham, Bob Chen +3
Third sound is studied for superfluid films of 4He adsorbed on multiwall carbon nanotubes packed into an annular resonator. The third sound is generated with mechanical oscillation…
