Talk:Quantum key distribution/to do


 * Enlarge and correct the E91 section: The "S" in the E91 section is not defined. Further, the section has $$|S|=-2\sqrt{2}$$ which is not possible as it has a nonnegative equal to a negative.
 * Add other protocol descriptions (CV, B92, DPS, SARG04 etc.)
 * Illustrate with diagrams, and maybe photos of a QC setup
