Comment on "Determining angle of arrival of radio-frequency fields using subwavelength, amplitude-only measurements of standing waves in a Rydberg atom sensor"
M. Chilcott, N. Kjærgaard
We discuss the consequence of excluding allowed RF-transition between substates of a field-dressed Rydberg manifold when predicting the spectrum that will be observed if the dresse…
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…
Counterdiabatic driving for random-gap Landau-Zener transitions
Georgios Theologou, Mikkel F. Andersen, Sandro Wimberger
The Landau--Zener (LZ) model describes a two-level quantum system that undergoes an avoided crossing. In the adiabatic limit, the transition probability vanishes. An auxiliary cont…
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…
