Quantum Code Key Produced at More Than 4 Mb/s

Facebook X LinkedIn Email
A team of researchers at the National Institute of Standards and Technology in Gaithersburg, Md., has developed a quantum key distribution system that generates code keys over a 1-km length of SMF-28 optical fiber from Corning Inc. in New York at 4.14 Mb/s and over a 4-km span of the fiber at nearly 1 Mb/s. The group presented a report on its work at the SPIE Defense & Security Symposium in Orlando, Fla., on April 18. The cryptography system relies on the no-cloning theorem in quantum mechanics to guarantee that a code key for subsequent encryption can be produced without the threat of...Read full article
