Quantum cryptography offers spy-proof code

Stolen banking and credit card information, compromised medical and financial records, tapping into cell phone conversations…

A team of researchers from the University of Calgary are hoping to put an end to these daily threats by using the theory of quantum physics to develop a spy-proof code.

Their initiative is based on the fact that information delivered via quantum cryptography presents a formidable challenge to hackers.

Should an unauthorized person try to intercept a quantum coded message, the data – much like a booby-trapped suitcase in a James Bond movie – blows up…figuratively, of course.

Any attempt to intercept the data alters its configuration and scrambles the message, says Wolfgang Tittel, physicist and principal researcher at the university’s Centre for Information Security and Cryptography.
