GS-2M: Material-aware Gaussian Splatting for High-fidelity Mesh Reconstruction
Dinh Minh Nguyen, Malte Avenhaus, Thomas Lindemeier
We propose a material-aware optimization framework for high-fidelity mesh reconstruction from multi-view images based on 3D Gaussian Splatting, referred to as GS-2M. Previous works…
Time-frequency quantum process tomography of parametric down-conversion
Malte Avenhaus, Benjamin Brecht, Kaisa Laiho +1
Parametric down-conversion (PDC) is the established standard for the practical generation of a multiplicity of quantum optical states. These include two-mode squeezed vacuum, heral…
Bright Integrated Photon-Pair Source for Practical Passive Decoy-State Quantum Key Distribution
Stephan Krapick, Michael Stefszky, Michal Jachura +3
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-reso…
Characteristics of displaced single photons attained via higher order factorial moments
Kaisa Laiho, Malte Avenhaus, Christine Silberhorn
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 l…
Accessing higher order correlations by time-multiplexing
M. Avenhaus, K. Laiho, M. V. Chekhova +1
We experimentally measured higher order normalized correlation functions (nCF) of pulsed light with a time-multiplexing-detector. We demonstrate excellent performance of our device…
Fiber-assisted single-photon spectrograph
Malte Avenhaus, Andreas Eckstein, Peter J. Mosley +1
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 ultra…
