Flux Crosstalk Calibration from Zero Knowledge to High Precision in Fully Tunable Superconducting Circuits
Y. Gao, A. Galicia, J. R. Guimarães +9
Precise and independent flux control is essential for scalable superconducting processors built from frequency-tunable qubits and couplers, but flux crosstalk undermines it. Conven…
Quantum environment afterglow from broadband excitation spectroscopy in superconducting qubits
J. R. Guimarães, Y. Liu, Y. Gao +10
Understanding the qubit environment is central to fault-tolerant superconducting quantum computation. Characterization typically relies on relaxation, leaving excitation largely un…
Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
Highly crystalline superconducting TiN resonators grown on thermally reconstructed sapphire
Thomas J. Smart, Marc Neis, Janine Lorenz +15
High quality crystalline growth of a thin film on sapphire requires sufficient substrate preparation, often achieved via the use of aggressive chemical cleaning. Direct thermal rec…
