How do Alice and Bob detect if their key generation process has been compromised during QKD?
In the field of Quantum Cryptography, specifically in the context of Practical Quantum Key Distribution (QKD), Alice and Bob employ various techniques to detect if their key generation process has been compromised. QKD is a cryptographic protocol that utilizes the principles of quantum mechanics to establish secure communication channels between two parties. The primary goal
What is the purpose of parameter estimation in classical post-processing in quantum key distribution protocols?
Parameter estimation plays a crucial role in classical post-processing in quantum key distribution (QKD) protocols. The purpose of parameter estimation is to accurately estimate the parameters that characterize the quantum states and measurements used in the QKD protocol. These parameters include the error rates of the quantum channel, the quantum bit error rate (QBER), and
