A Faithful Communication Hamiltonian in Photonic Lattices    [PDF]

Matthieu Bellec, Georgios M. Nikolopoulos, Stelios Tzortzakis
Faithful communication is a necessary precondition for large scale all-optical networking and quantum information processing. Related theoretical investigations in different areas of physics have led to various proposals in which finite discrete lattices are used as channels for short-distance communication tasks. Here, in the framework of femtosecond-laser-written waveguide arrays, we present the first experimental realization of such a channel with judiciously engineered couplings.
