Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can't be copied or split and thus are secure—in the network of optical fibers we already have. This opens up a broad range of applications relying on secure quantum information. The research is published in the journal Nature Nanotechnology.
