A longstanding quantum roadblock just fell, opening existing fiber networks to ultra-secure light signals - Phys.org

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 relyi…
