Concepts for Data-Security of Future Communication

The term entanglement is used in quantum theory to describe the way that particles of energy/matter can become correlated and predictably interact with each other regardless of how far apart they are. In future quantum entanglement will dominate the way we look at information, the way we communicate secretly and the way our computers do their things. Much current research is focusing on how to harness the potential of entanglement in developing quantum key distribution system. Quantum key distribution is going to be the only solution for future secure communication. In this paper we have presented concept of entanglement in a simple and innovative way. We have also summarized the necessary concept of superposition and measurement effect that are basement of entanglement property. At last we have discussed quantum key distribution concepts. These will work as guideline in designing quantum key distribution system using entanglement.
