Modeling of simple bandpass filters: bandwidth broadening of Josephson parametric devices due to non-Markovian coupling to dressed transmission-line modes
Rui Yang, Zheng Shi, Zhirong Lin +1
Josephson parametric devices are widely used in superconducting quantum computing research but suffer from an inherent gain-bandwidth trade-off. This limitation is partly overcome…

Simulation of a rapid qubit readout dependent on the transmission of a single fluxon
Waltraut Wustmann, Kevin D. Osborn
The readout speed of qubits is a major limitation for error correction in quantum information science. We show simulations of a proposed device that gives readout of a fluxonium qu…
