Exploring Quantum Encryption for Secure Messaging Against Cyber Threats

No matter how complex they are, most secret codes turn out to be breakable. Producing the ultimate secure code may require encoding a secret message inside the quantum relationship between atoms, scientists say. Now cryptographers have taken "quantum encryption" a step further by showing how a secret message can remain secure even if the system is compromised by a malicious hacker.

Artur Ekert, director of the Center for Quantum Technologies at the National University of Singapore, presented the new findings here at the annual meeting of the American Association for the Advancement of Science.
