The ability to integrate electronic circuits into semiconductor microstructures has laid the foundation of modern information and communication technology. Quantum information could bring about a second information revolution, but not until scientists develop the technology needed for microscopic circuits that can be built on a large scale. Researchers from France and Switzerland have now produced an integrated semiconductor source of pairs of single photons, which are a crucial ingredient for optical quantum information processing. Their advance is a promising step towards chip-based quantum information technologies.
