Secure metropolitan quantum networks move a step closer

Successful new field tests of a continuous-variable quantum key distribution (CV-QKD) system over commercial fiber networks could pave the way to its use in metropolitan areas. That is the key achievement from a team of scientists, which demonstrates CV-QKD transmission over commercial deployed fiber link with a distance of 50 kilometers.
