The creation of quantum-correlated photon pairs is a necessary step toward realizing quantum simulation and ultimately quantum computing. Using a millimeter-scale silicon-on-insulator chip, scientists successfully separate correlated photon pairs from background pump photons, where the latter are more numerous by a factor exceeding 10 billion.
