Quantum State Tomography for Optical Soliton Molecules — •Oskar Schlettwein, Kai Barnscheidt, Jakob Studer, and Boris Hage — Arbeitsgruppe Experimentelle Quantenoptik, Institut für Physik, Universität Rostock, D-18059 Rostock, Germany

Bright pulses in optical fibers mainly experience dispersion, the Kerr-effect as well as (stimulated) Brillouin and Raman scattering. The scattering processes introduce phase noise which becomes important for applications at or below the shot noise limit. In contrast to Brillouin scattering the impact of the Raman effect on quantum states is not clear. Numerical simulation as well as a quantum state tomographic setup for bright pulsed signals will be presented to provide deeper insight about it. The setup allows a full quantum state reconstruction of Kerr squeezed states.

Utilizing dispersion managed (DM) fibres the quantum state of DM-solitons can be studied. Extending our system to a two mode quantum state tomograph will lead the way to probe quantum correlations in soliton molecules. This stable configuration of two or more DM-solitons could provide a fruitful source for new fiber based quantum communication application.
