Universal Statistics of Energy and Information Flow in Random Electromagnetic Fields
Yuchen Ke, Nandini Bhattacharya, Stefan Rotter +1
We establish a universal statistical description for the local flow of energy and information in random electromagnetic fields. The longitudinal Poynting flux, written as a Hermiti…
Enabling Deterministic Passive Quantum State Transfer with Giant Atoms
Oliver Diekmann, Enrico Di Benedetto, Nicolas Jungwirth +7
Achieving quantum state transfer in passive ways can become a powerful asset for scalable quantum networks. Here, we demonstrate how giant atoms coupled to 1D waveguides provide a…
Massively Degenerate Coherent Perfect Absorption in Gradient-Index Fibers
Helmut Hörner, Åahin K. Ãzdemir, Stefan Rotter
Coherent perfect absorbers (CPAs) have recently attracted considerable attention due to their ability to enhance light--matter interaction. By exploiting interference, CPAs enable…
Passive quantum state transfer in a dispersion-engineered waveguide
Zeyu Kuang, Oliver Diekmann, Lorenz Fischer +2
High-fidelity state transfer is fundamentally limited by time-reversal symmetry: one qubit emits a photon with a certain temporal pulse shape, whereas a second qubit requires the t…
Self-Induced Superradiant Masing
Wenzel Kersten, Nikolaus de Zordo, Oliver Diekmann +9
In cavity quantum electrodynamics (cQED) and particularly superradiance, emitters are typically assumed to be independent, interacting only through light shared via a common mode.…
