Hacker-proof data link

PTBnews 3.2022

The existing optical fiber link for time and frequency transmission between PTB and Leibniz University Hannover is being upgraded to a test link for quantum communication. The project InterSync, which is receiving 1.5 million euros in funding from the German Research Foundation (DFG), is establishing a tap-proof data link between the two facilities which are more than 70 km apart. A team of scientists is researching and presenting a new, precise time synchronization method specifically for use in quantum networks and quantum cryptography. The project is being coordinated by Leibniz University. (Contact at PTB: Stefan Kück, +49 531 592-4010, Opens local program for sending emailstefan.kueck(at)ptb.de)
