Quantum communication through synergy

(PhysOrg.com) -- When most people think of quantum communication, they think in terms of private communication channels - the ability to send messages without a third-party deciphering them. Indeed, quantum cryptography represents a method of sending information that cannot be eavesdropped upon. Without the proper key for decoding the intercepted message, all an interloper would receive is gibberish. To make quantum cryptography work, Graeme Smith tells PhysOrg.com, “We try to understand the protocols and use specially designed channels to send messages and also to shed light on the general theory of privacy in quantum mechanics.”
