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.

BB84 protocol

The BB84 protocol represents a foundational achievement in quantum cryptography. Developed by Charles Bennett and Gilles Brassard in 1984, it employs polarized photons to generate and share encryption keys. Its significance lies in leveraging quantum mechanics—specifically the uncertainty principle—to create a system inherently resistant to traditional eavesdropping methods. The protocol is primar...
