Simulation of the BB84 protocol

This project simulates the BB84 protocol, proposed by Bennett & Brassard in 1984, using PennyLane. It demonstrates the protocol's robustness through probabilistic metrics such as entropy and mutual information.

Description

This is an exploratory, educational implementation aimed at illustrating the security of the BB84 quantum key distribution protocol.
