Abstract
Current cyber security solutions rely on ever increasing secret keys. The alternative solution to this trend is to use quantum security schemes. A quantum security scheme insures that there is no mathematical computation that allows for the computation of the key, as it is simply random. The present paper describes a quantum key distribution scheme that exploits correlation between pairs of bits. This new feature has the added quality that the intruder-Eve can be detected even on a qubit that Eve has not tampered with. The security of the protocol can be made arbitrarily high by increasing the safety parameter.
