This crystal can split light particles

The video explores the fascinating world of quantum entanglement and the role of nonlinear crystals in creating entangled photons. It explains the process of parametric downconversion, where a single photon is split into two, and the importance of energy and momentum conservation. The video also highlights various applications of nonlinear crystals, such as creating UV lasers and testing human visual sensitivity to single photons.
