Quantum Key Distribution
Bhavesh B. Prajapati, Nirbhay Kumar Chaubey
Abstract
Quantum key distribution is an application of quantum cryptography which is based on quantum mechanics and optical physics. The word “quantum” means the smallest particle of matter and energy which inhibits unique special properties to make it different from normal matter. This chapter discusses underlying principles, and operations of quantum mechanics which are used to derive quantum key distribution protocols. This chapter also discusses elementary QKD protocols based on no cloning theorem and EPR correlations. Limitation of quantum key distribution is also discussed with reference to its implementation. Conceptual notes on quantum internet are also given.
