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…

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.…
