description Overview

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.

GHZ state

A Greenberger–Horne–Zeilinger (GHZ) state is a specific entangled quantum state of three or more particles where measuring the properties of one instantaneously influences the possible outcomes for all others, regardless of distance.
