Using the Hog-Ou-Mandel effect for imaging The Hong-Ou-Mandel (HOM) effect is a cornerstone of modern quantum optics. Originally proposed and demonstrated in 1987 by Chung-Ki Hong, Zhe-Yu Ou, and...
Quasi phase matching with periodic poling The generation of pure nonclassical states of light is one of the most important goals of optical quantum information science. A popular...
Introduction to Spatial Entanglement in SPDC One of the most remarkable features of quantum theory is entanglement, where quantum systems show nonlocal correlations between particles or photons that are...
Induced coherence and imaging with undetected photons One of the most beautiful experiments with SPDC light is that of induced coherence. It has originally been demonstrated and analyzed by...
The birth of SPDC photons In nonlinear crystals, a special nonlinear process occurs. A pump photon is spontaneously converted into two complementary photons with lower energy. In this process...
