The fidelity between the shared state and the maximally entangled state is a critical metric in determining the security of the BB84 protocol, a cornerstone of quantum key distribution (QKD). To understand this relationship, it is essential to consider the fundamentals of quantum cryptography, the principles underlying the BB84 protocol, and the role of entanglement
