Today nearly all of the people are involved in communicating each other with the help of online communication. Nearly three fourth of the world are connected via social media.So it is very important to secure the data transmission between the user. And in addition to this future of computer’s will be of by Quantum technologies. So the In this paper we are going to see how to increase the security of online transmission through Quantum shift distribution algorithm. In this paper idea outlines the implementation of this most advanced level of encryption by Quantum Key Distribution method and importance of quantum cryptography in future.
