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…
Qubit-efficient quantum combinatorial optimization solver
Bhuvanesh Sundar, Maxime Dupont
Quantum optimization solvers typically rely on one-variable-to-one-qubit mapping. However, the low qubit count on current quantum computers is a major obstacle in competing against…
Simulating nonlinear optical processes on a superconducting quantum device
Yuan Shi, Bram Evert, Amy F. Brown +8
Simulating plasma physics on quantum computers is difficult because most problems of interest are nonlinear, but quantum computers are not naturally suitable for nonlinear operatio…
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-…
