How does the mutual information between Alice and Eve change as the disturbance introduced by Eve increases?
The mutual information between Alice and Eve is a fundamental concept in the field of quantum cryptography, specifically in the context of the security of quantum key distribution (QKD) protocols. It quantifies the amount of information that Eve, an eavesdropper, can potentially gain about the secret key shared between Alice and Bob, the legitimate parties.
What is the purpose of analyzing the mutual information between Alice and Eve in quantum key distribution?
Analyzing the mutual information between Alice and Eve in quantum key distribution serves a crucial purpose in ensuring the security of the communication channel. In the field of quantum cryptography, the primary objective is to establish a secure and secret key between two parties, Alice (the sender) and Bob (the receiver), in the presence of

How does the mutual information between Alice and Bob and Alice and Eve vary for different quantum key distribution protocols?
The mutual information between Alice and Bob, and Alice and Eve, can vary for different quantum key distribution (QKD) protocols. In the field of cybersecurity, specifically in quantum cryptography fundamentals, the security of QKD against eavesdropping strategies is a crucial aspect to consider. To understand the variation in mutual information, let's first define what mutual
