Enhanced Superconducting Qubit Performance Through Ammonium Fluoride Etch
Cameron J. Kopas, Dominic P. Goronzy, Thang Pham +19
The performance of superconducting qubits is often limited by dissipation and two-level systems (TLS) losses. The dominant sources of these losses are believed to originate from am…
Precision frequency tuning of tunable transmon qubits using alternating-bias assisted annealing
Xiqiao Wang, Joel Howard, Eyob A. Sete +13
Superconducting quantum processors are one of the leading platforms for realizing scalable fault-tolerant quantum computation (FTQC). The recent demonstration of post-fabrication t…
Quantifying fault tolerant simulation of strongly correlated systems using the Fermi-Hubbard model
Anjali A. Agrawal, Joshua Job, Tyler L. Wilson +8
Understanding the physics of strongly correlated materials is one of the grand challenge problems for physics today. A large class of scientifically interesting materials, from hig…
Superconducting qubits in the millions: the potential and limitations of modularity
S. N. Saadatmand, Tyler L. Wilson, Mark J. Hodson +11
The development of fault-tolerant quantum computers (FTQCs) is receiving increasing attention within the quantum computing community. Like conventional digital computers, FTQCs, wh…
Transport signatures of phase fluctuations in superconducting qubits
Maxwell Wisne, Yanpei Deng, Hilal Cansizoglu +3
Josephson junctions supply the nonlinear inductance element in superconducting qubits. In the widely used transmon configuration, where the junction is shunted by a large capacitor…
Formation and Microwave Losses of Hydrides in Superconducting Niobium Thin Films Resulting from Fluoride Chemical Processing
Carlos G. Torres-Castanedo, Dominic P. Goronzy, Thang Pham +18
Superconducting Nb thin films have recently attracted significant attention due to their utility for quantum information technologies. In the processing of Nb thin films, fluoride-…
Error budget of parametric resonance entangling gate with a tunable coupler
Eyob A. Sete, Vinay Tripathi, Joseph A. Valery +2
We analyze the experimental error budget of parametric resonance gates in a tunable coupler architecture. We identify and characterize various sources of errors, including incohere…
Alternating Bias Assisted Annealing of Amorphous Oxide Tunnel Junctions
David P. Pappas, Mark Field, Cameron Kopas +10
We demonstrate a transformational technique for controllably tuning the electrical properties of fabricated thermally oxidized amorphous aluminum-oxide tunnel junctions. Using conv…
