The bagel they save for the regulars. Don't skim, savour.
Summary
Researchers at Xiamen University in China have demonstrated that correlated photon pairs, essential for quantum optics experiments, can be generated using sunlight as the pump source for spontaneous parametric down-conversion in a nonlinear crystal. This breakthrough eliminates the need for complex laser systems typically required to produce entangled photons. The technique, known as ghost imaging, could enable quantum optics experiments in space or other locations with limited electricity, significantly broadening the accessibility of quantum research.
