description Overview

E91 protocol

The E91 protocol is a foundational experiment in quantum mechanics utilizing three entangled photons. Developed by Artur Ekert in 1991, it rigorously tests Bell's inequalities through measurements performed in different orientations. This work demonstrates the violation of local realism, confirming that quantum correlations are fundamentally stronger than any possible classical explanation. The pr...

GHZ state

The GHZ state represents a fundamental entanglement phenomenon involving multiple quantum particles. It’s notable because measurement on any particle within this state immediately determines correlated properties across all other entangled particles, irrespective of separation. This state is particularly relevant for researchers investigating the foundations of quantum mechanics and exploring mult...
