Quantum communication with integrated optics

Integrated optic devices – such as optical fibers, waveguides or linear optical circuits – in combination with pulsed quantum light and time-multiplexing configurations offer distinct advantages to realize photonic quantum systems for quantum information applications. The experimental setups get miniaturized, the spatial properties of generated quantum states are defined by the guiding geometries and networks are intrinsically stable. We present our toolbox for the realization of future quantum devices, including engineered genuine single-mode pulsed quantum light and a high dimensional quantum walk experiment.
