BBM92 protocol
Quantum protocol without Bell theorem From Wikipedia, the free encyclopedia
BBM92 is a quantum key distribution without Bell's theorem developed using polarized entangled photon pairs by Charles H. Bennett, Gilles Brassard and N. David Mermin in 1992.[1] It is named after the trio's surnames as (Bennett, Brassard and Mermin, BBM92).[2] It uses decoy state of multiple photon instead of single. The key differences in E91 protocol and B92[3] uses only two states instead of four states used by E91 protocol and BB84

It is used for non orthogonal quantum transmission 0 can be encrypted as 0 degree and 1 as 45 degree in diagonal basis BB92 protocol. There are no eavesdropping secure and hack proof [4][5][6][7] for distance of 200–300 m.
