Characterization of Aluminum Microwave SQUID Multiplexers for CENS Detection
James Amidei, Antoine Armatol, Corinne Augier +92
We present the design, fabrication, and characterization of an aluminum-based six-channel microwave SQUID multiplexer (MUX) prototype for transition-edge sensor (TES) readout in…
Gate-dependent offset charge shifts and anharmonicity in gatemon qubits in the weak tunneling regime
Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3
Gatemon qubits are based on a superconductor-quantum dot-superconductor (S-QD-S) junction which enables in situ electrostatic tuning via a gate electrode. For a single-channel QD t…
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…
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…
Abatement of Ionizing Radiation for Superconducting Quantum Devices
B. Loer, P. M. Harrington, B. Archambault +15
Ionizing radiation has been shown to reduce the performance of superconducting quantum circuits. In this report, we evaluate the expected contributions of different sources of ambi…
G4CMP: Condensed Matter Physics Simulation Using the Geant4 Toolkit
M. H. Kelsey, R. Agnese, Y. F. Alam +44
G4CMP simulates phonon and charge transport in cryogenic semiconductor crystals using the Geant4 toolkit. The transport code is capable of simulating the propagation of acoustic ph…
