Floquet-Nambu theory of electron quantum optics with superconductors
Pablo Burset, Benjamin Roussel, Michael Moskalets +1
We present a comprehensive Floquet-Nambu theory to describe the time-dependent quantum transport in mesoscopic circuits involving superconductors. The central object of our framewo…
Quantum sensing of time dependent electromagnetic fields with single electron excitations
H. Souquet-Basiège, B. Roussel, G. Rebora +4
In this study, we investigate the potential of electronic interferometers for probing the quantum state of electromagnetic radiation on a chip at sub-nanosecond time scales. We pro…
Wigner representation of Andreev-reflected charge pulses
Benjamin Roussel, Pablo Burset, Christian Flindt
Recent experiments have shown that the edge states of a quantum Hall sample can be coupled to a superconductor, so that incoming electrons in the edge states can be Andreev convert…
On-Demand and Tunable Andreev-Conversion of Single-Electron Charge Pulses
Pablo Burset, Benjamin Roussel, Michael Moskalets +1
Electron quantum optics explores coherent single-electron charge pulse propagation in electronic nanoscale circuits akin to table-top photon setups. While past experiments focused…
