Abstract: In this paper the experimental and the numerical study of an optical key distribution quantum cryptography using BB84 protocol has been achieved. We create secret quantum key and the security of BB84 protocol is tested by inserting Eve in the system, the presence of Eve will cause disturbance to the synchronization of qubits between Alice and Bob and lead to bits errors. Finally we enhance the security of quantum cryptography using one-time pad technique and chaotic signal generated by semiconductor laser with an optical feedback. Mixing quantum key with chaotic signal will make ultimate security of the system.
