Abstract

See full text

An apparatus and method for implementing a quantum cryptography system that requires fewer random bits. The emitter divides the key in blocks of bits. Instead of changing the basis for each bit of key sent by the emitter, the same basis is used for all the bits within a block. By doing this, the rate of random bits of information necessary for the implementation of a secure quantum cryptography link is reduced.
