Quantum encryption technique secures full high-speed data stream

摘要

Evanston, Ill. - A quantum encryption system developed by two Northwestern University professors can encode entire high-speed data streams and po- tentially could encrypt data sent at Internet backbone speeds, its inventors said. Prem Kumar and Horace Yuen use quantum codes to encrypt the signal transmitted down the Internet's optical-fiber backbone. "No one else is doing quantum encryption at these high speeds," Kumar said.
