Could there perhaps be some explanation of the overview statement "Alice must tell Bob which gate to apply after he receives the entangled qubit in order to obtain the correct classical bits." It does not seem to be explained anywhere. <!-- Template:Unsigned IP --><small class="autosigned">— Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/118.209.183.247|118.209.183.247]] ([[User talk:118.209.183.247#top|talk]]) 14:36, 10 January 2019 (UTC)</small> <!--Autosigned by SineBot--> now signed by [[Special:Contributions/118.209.183.247|118.209.183.247]] ([[User talk:118.209.183.247|talk]]) 10:29, 12 January 2019 (UTC)johnjPerth
== Deceptive video? ==
The video "Video superdense coding.ogg" seems to be selling an idea that isn't true. In the video A is connected to B via a single wavy line. This is contrary to the protocol which requires two qubits. The article even says "Without access to Bob's qubit, Eve is unable to get any information from Alice's qubit." The description in the External link "Superdense coding: how to send two bits using one qubit on YouTube by Michael Nielsen" is not as pretty, but much more accurate.
