QuTech and Eurofiber run quantum cryptography on existing fiber in an open testbed

QuTech and Eurofiber, together with QuTech spin-out Q*Bird and other partners, have installed a proof-of-concept quantum communication system between locations in the Utrecht area. The testbed shows that it is possible to build secure communication using carrier grade dark fiber connections, integrating conventional network equipment in a quantum encryption environment. Current cryptography methods are ...
