Photon counting beyond the rotating-wave approximation
Steven Kim, Fabian Hassler
Open quantum systems are often described by a Lindblad master equation, which relies on a set of approximations, most importantly the rotating-wave approximation which is only vali…
Quantum Synchronization of Fock States
Fabian Hassler, David Scheer, Samah Saquaque +1
Synchronization, a ubiquitous phenomenon in classical systems, has recently been extended to the quantum domain. Here, we show quantum synchronization of a bosonic mode exhibiting…
Robust gap closing and reopening in topological-insulator Josephson junctions
Jakob Schluck, Ella Nikodem, Anton Montag +4
In the seminal proposal by Fu and Kane, the superconducting proximity effect is used to realize topological superconductivity in the topological surface state (TSS) of a 3D topolog…
Topological quantum computing
Fabian Hassler
These lecture notes offer a pedagogical yet concise introduction to topological quantum computing. The material focuses on topological superconductors and Majorana qubits. It concl…
