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—...
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...
Device-independent Quantum Key Distribution (DI-QKD) offers a fundamentally more secure approach to cryptography. It establishes quantum keys based purely on observed quantum correlations, eliminating reliance on device assumptions. This technology is particularly valuable for applications demanding...
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.
