description Overview

B92 protocol

B92 is a quantum communication protocol utilizing two non-orthogonal polarization states of single photons to enable secure key distribution and potentially teleportation, differing from BB84 by its unique state selection approach.

E91 protocol

E91 is a quantum entanglement protocol demonstrating non-local realism violation; it uses three entangled photons and measurements in multiple bases to prove Bell inequality's failure, indicating quantum correlations exceeding classical limits.
