An international team of researchers has demonstrated high-visibility quantum interference between two independent quantum dots (QDs) connected by approximately 300-kilometer (km)/186.4-mile optical fibers.

The arrangement generates single photons from resonantly driven single QDs paired with microcavities.

Explained Chao-Yang Lu at the University of Science and Technology of China, “Our work jumped from the previous QD-based quantum experiments at a scale from [about] 1 km to 300 km, two orders of magnitude larger, and thus opens an exciting prospect of solid-state quantum networks."

Lu added, "Feasible improvements can further extend the distance to about 600 km."
