Quantum – a double-edged sword for cryptography

Cryptography that would be impossible for a regular computer to crack, would take a quantum computer just seconds.

Quantum computers pose a big threat to the security of modern communications, deciphering cryptographic codes that would take regular computers forever to crack. But drawing on the properties of quantum behaviour could also provide a route to truly secure cryptography. Defence, finance, social networking – communications everywhere rely on cryptographic security. Cryptography involves jumbling up … Read more
