Abstract
Cryptography consists in sending a message to a correspondent and in minimizing the risk of this message being intercepted by an unwanted outsider. The present problem shows how quantum mechanics can provide a procedure to achieve this goal. We assume here that Alice (A) wants to send Bob (B) some information which may be coded in the binary system, for instance
We denote the number of bits of this message by n. Alice wants to send this message to Bob only if she has made sure that no “spy” is listening to the communication.
