We investigate up to the fourth order normalized factorial moments of free-propagating and pulsed single photons displaced in phase space in a phase-averaged manner. Due to their loss independence, these moments offer expedient methods for quantum op

This contribution introduces an approach for stitching multiple images of a histological slide to a panorama image using Differences of Paraboloids (DOP). DOP provides a novel method for the detection, description and matching of features of two over

We report on a bright, nondegenerate type-I parametric down-conversion source, which is well suited for passive decoy-state quantum key distribution. We show the photon-number-resolved analysis over a broad range of pump powers and we prove heralded

We experimentally measured higher order normalized correlation functions (NCF) of pulsed light with a time-multiplexing detector. We demonstrate excellent performance of our device by verifying unity valued NCF up to the eighth order for coherent lig

Heralded pure single photons are an indispensable resource for linear optical quantum computing (LOQC), as the fidelity of single photon quantum gates depends critically on the state purity of the input ancilla photons. The heralded photon's purity r

For many experiments in quantum optics like homodyne detection or heralded state preparation it is essential to learn about the spectral structure of the quantum mechanical states under study [1,2]. Typically, in these experiments the requirement of

We study the ability to measure the non-Gaussian character of the single photon Fock states via direct measurements of the photon number statistics of displaced quantum states.

We study the spectral properties of spontaneous parametric down-conversion (SPDC) in a periodically poled waveguided structure of potassium-titanyl-phosphate (KTP) crystal pumped by ultrashort pulses. Our theoretical analysis reveals a strongly entan

We demonstrate the implementation of a fiber-integrated spectrograph utilizing chromatic group velocity dispersion (GVD) in a single mode fiber. By means of GVD we stretch an ultrafast pulse in time in order to spectrally resolve single photons in th
