"Quantum dense coding" and "Superdense coding" mean the same thing. The two articles should be merged asa proposed. Cryptonaut 02:36, 25 April 2006 (UTC)[reply]

I agree, merge 'em. —Keenan Pepper 02:45, 25 April 2006 (UTC)[reply]

Correction for diagram.

A IP user has requested that the diagram on this page the modified. They wrote: "Please flip b_1 and b_2 on sender's side! Thanks!" into the figure caption. I am moving the request here where it should be. I would make the change myself, but I'm not sure that it's actually correct or not. —♫CheChe♫ talk 15:21, 16 October 2017 (UTC)[reply]

Oh, also, I'm thinking of making a new SVG version of the diagram. If anyone can confirm that the requested change is correct, I would be happy to get on that. —♫CheChe♫ talk 15:23, 16 October 2017 (UTC)[reply]

The current version of the diagram is correct. --Robin (talk) 23:26, 16 June 2018 (UTC)[reply]

"Why"

The esteemed editor who keeps pondering "why" has apparently been too kind to point out both the transformations and their results are wrong. So much for "Details".

current experimental applications of superdense coding

This page is missing experimental results even though the field is very active. For example:

this was the first experimental demonstration of superdense coding, where they achieved 1.58 bits per qubit (not a perfect 2): https://journals.aps.org/prl/pdf/10.1103/PhysRevLett.76.4656 (they used polarization of photons).

This year researchers exceeded the two-bit limit using high dimensional entanglement. http://advances.sciencemag.org/content/4/7/eaat9304

This group was the first transmit superdense coding over optical fiber. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.118.050501 — Preceding unsigned comment added by Donaldfee (talk • contribs) 21:18, 30 November 2018 (UTC)[reply]
