Scaling Quantum Connectivity: Researchers Achieve 13-Photon Multipartite Entanglement

A significant breakthrough in photonic quantum information has been achieved by successfully entangling 13 photons. This milestone overcomes previous technical barriers in creating complex multipartite states, paving the way for larger, reconfigurable quantum networks.

A highway instead of a racetrack: Strong coupling of light and sound in an optical fiber

For the first time, scientists have achieved strong coupling between light and long-lived acoustic vibrations in an optical fiber. Optical fibers are used in both classical telecommunications and quantum communication and could serve not only as connections between computing nodes but also as quantum processors themselves in the future. The results, published in Nature Physics, pave the way for new technologies in quantum signal processing.
