What is the difference between BBM92 and BB84?
I am interested in understanding the distinction between two quantum key distribution protocols, BBM92 and BB84. Could someone please explain the main differences between these two protocols?
Why is BB84 secure?
BB84 is secure because it utilizes the principles of quantum mechanics, specifically the no-cloning theorem and quantum entanglement, to ensure that any eavesdropping or tampering with the transmitted information will be detected, thus guaranteeing the secrecy and integrity of the communication.
