Driven Gaussian quantum walks
Philip Held, Melanie Engelkemeier, Syamsundar De +3
Quantum walks function as essential means to implement quantum simulators, allowing one to study complex and often directly inaccessible quantum processes in controllable systems.…
Climbing the Fock ladder: Advancing multiphoton state generation
M. Engelkemeier, J. Sperling, J. Tiedau +5
A scheme for the enhanced generation of higher photon-number states is realized, using an optical time-multiplexing setting that exploits a parametric down-conversion source for an…
Quantum optical coherence: From linear to nonlinear interferometers
K. -H. Luo, M. Santandrea, M. Stefszky +6
Interferometers provide a highly sensitive means to investigate and exploit the coherence properties of light in metrology applications. However, interferometers come in various fo…
Quantifying quantum coherence in polariton condensates
Carolin Lüders, Matthias Pukrop, Elena Rozas +5
We theoretically and experimentally investigate quantum features of an interacting light-matter system from a multidisciplinary perspective, unifying approaches from semiconductor…
Experimental entanglement characterization of two-rebit states
Nidhin Prasannan, Syamsundar De, Sonja Barkhofen +3
We characterize entanglement subject to its definition over real and complex, composite quantum systems. In particular, a method is established to assess quantum correlations with…
Probing the topological Anderson transition with quantum walks
Dmitry Bagrets, Kun Woo Kim, Sonja Barkhofen +5
We consider one-dimensional quantum walks in optical linear networks with synthetically introduced disorder and tunable system parameters allowing for the engineered realization of…
