End-to-end meta-imagers: Information-theoretic objectives and generalized focusing optima
Lukas Kienesberger, Zeyu Kuang, Yaxi Liu +1
Metasurfaces and complex photonic components are increasingly co-designed with computational back-ends via end-to-end optimization, yet such optimizations are expensive and opaque…
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…
Dynamic and Geometric Shifts in Wave Scattering
Konstantin Y. Bliokh, Zeyu Kuang, Stefan Rotter
Since Berry's pioneering 1984 work, the separation of geometric and dynamic contributions in the {\it phase} of an evolving wave has become fundamental in physics, underpinning div…
