Spatio-spectral characteristics of parametric down-conversion in waveguide arrays
Regina Kruse, Fabian Katzschmann, Andreas Christ +7
High dimensional quantum states are of fundamental interest for quantum information processing. They give access to large Hilbert spaces and, in turn, enable the encoding of quantu…
Increasing the dimensionality of quantum walks using multiple walkers
Peter P. Rohde, Andreas Schreiber, Martin Stefanak +3
We show that with the addition of multiple walkers, quantum walks on a line can be transformed into lattice graphs of higher dimension. Thus, multi-walker walks can simulate single…
A 2D Quantum Walk Simulation of Two-Particle Dynamics
Andreas Schreiber, Aurel Gabris, Peter P. Rohde +6
Multi-dimensional quantum walks can exhibit highly non-trivial topological structure, providing a powerful tool for simulating quantum information and transport systems. We present…
Photon propagation in a discrete fiber network: An interplay of coherence and losses
Alois Regensburger, Christoph Bersch, Benjamin Hinrichs +4
We study light propagation in a photonic system that shows stepwise evolution in a discretized environment. It resembles a discrete-time version of photonic waveguide arrays or qua…
Zitterbewegung, Bloch Oscillations and Landau-Zener Tunneling in a Quantum Walk
Alois Regensburger, Christoph Bersch, Benjamin Hinrichs +4
We experimentally investigate a discrete time quantum walk in a system of coupled fiber loops and observe typical phenomena known from the wave propagation in periodic structures a…
Decoherence and disorder in quantum walks: From ballistic spread to localization
A. Schreiber, K. N. Cassemiro, V. Potoček +3
We investigate the impact of decoherence and static disorder on the dynamics of quantum particles moving in a periodic lattice. Our experiment relies on the photonic implementation…
