Quantum cryptography provides us with a method for two remote users to communicate in an unconditionally secure way. In this paper, we present a brief introduction of this new technique and activities in our laboratory to develop a practical cryptographic system using photonic technologies.

In this paper, the elementary aspects of quantum cryptography are presented. First, we start with the introduction and history of quantum cryptography. Second, we give the definition of classical and quantum cryptography and emphasize the difference between the two. The idea of quantum cryptography will be explained further in the subsequent section, where the famous quantum key distribution example is presented. Lastly, we give the results of some computer simulations.
