On the 15th of May, Patrick Bartkowiak defended his Master's thesis titled "Electro-Optical Modulation on the Basis of Directional Coupler in LiNbO3".

Physicists from the University of Paderborn have for the first time succeeded in realizing the key building blocks of quantum photonics, the full Hong-Ou-Mandel experiment showing the bunching of two single photons on a single chip. This is an important step for establishing the new quantum technology. It is needed e.g. for synchronization of quantum communications, building up quantum simulators, or quantum based high precision measurements. …
