Lecture
This lecture covers the key concepts of quantum cryptography, focusing on the generation of secret keys using the one-time pad protocol. Starting with an introduction to quantum information theory, it delves into the protocol proposed by Bennett and Brassard in 1984. The lecture explains the process of generating a shared secret key between two parties, Alice and Bob, through the exchange of quantum bits. It also discusses the security aspects of quantum key distribution and the role of Eve in intercepting the communication. The presentation concludes with a recap of the key generation and decoding procedures, emphasizing the importance of quantum principles in ensuring secure communication.
