The first quantum cryptographic exchange occurred in October 1989 at IBM’s Thomas J. Watson Research Centre near New York. Two computers called Alice and Bob successfully negotiated a completely secure channel of communication over a distance of 32 centimetres, making quantum cryptography a reality rather than just a theory.
In this paper we show why many now view quantum cryptography as the first ever completely unbreakable cipher, allowing secure and private communication around the globe. The paper will then examine the potential problems and implications that this could have on society.
