A 2D Quantum Walk Simulation of Two-Particle Dynamics

Andreas Schreiber, +13 more
- 06 Apr 2012 - 
TL;DR: An optical system is demonstrated that can simulate quantum walks over a two-dimensional system, thereby providing the capability of describing much more complex processes and illustrating the potential of quantum walks as a route for simulating and understanding complex quantum systems.
Journal ArticleDOI

Accessing higher order correlations in quantum optical states by time multiplexing.

Malte Avenhaus, +4 more
- 11 Feb 2010 - 
TL;DR: In this article, higher order normalized correlation functions (NCF) of pulsed light with a time-multiplexing detector were measured by verifying unity valued NCF up to the eighth order for coherent light and factorial dependence of the NCF for pseudothermal light.
Journal ArticleDOI

Photon number statistics of multimode parametric down-conversion.

Malte Avenhaus, +5 more
- 01 Aug 2008 - 
TL;DR: The results clearly reveal a difference between single-mode theoretical description and the measured distributions of parametric down-conversion, and assure the applicability of loss-tolerant photon number reconstruction.
Journal ArticleDOI

Probing the Negative Wigner Function of a Pulsed Single Photon Point by Point

Kaisa Laiho, +3 more
- 17 Dec 2010 - 
TL;DR: The negative region of the Wigner function of a single photon generated by the means of waveguided parametric down conversion is probed by employing loss-tolerant photon-number resolving detection, allowing us to directly observe the oscillations of the photon statistics in dependence of applied displacements in phase space.
Journal ArticleDOI

Spatial modes in waveguided parametric down-conversion

Andreas Christ, +5 more
- 18 Sep 2009 - 
TL;DR: In this paper, the results of higher-order spatial-mode propagation in nonlinear waveguides were investigated both theoretically and experimentally, and conditions for the creation of pairs in these modes were derived and observed in both the spatial and spectral domains.
