A Theoretical Approach of Multi-user Quantum Key Distribution

"The road to success runs through somebody's eyes, it always need a vision to step ahead." The work presented in this book is a step for the vision of entering into a communication era with higher security. Quantum mechanics is the need of futuristic communication technology so that the basic principles of it govern the security measures. Though there are lots of bottlenecks there and we seek certain modification in the theories. But we can say it for sure that next generation is of Quantum communication.
