Talk:Spekkens toy model

Hidden variables?
This article reads like the standard EPR-type hidden variables theory, which has been mostly disproved (at least those involving local action) by Bell's theorem and many experiments by Aspect, et.al.. Strangely, the only occurrence of the phrase "hidden variables" is in a separate list of links, not in the article itself. Since I'm not an expert, I will refrain from editing the article, but it needs clarification. David Spector (talk) 18:19, 7 December 2019 (UTC)
 * Indeed, this is a hidden-variable model, which bizarrely the article fails to mention. Also, the Spekkens toy model cannot reproduce nonlocality or contextuality. This is not a problem per se, as the toy model was never meant to do that, its purpose was to illustrate how many quantum phenomena can qualitatively be reproduced by a hidden-variables model. In any case, this is a really important point that the article fails to mention. I'll edit it to add the information. Tercer (talk) 10:16, 3 February 2020 (UTC)
 * The natural genralization of the toy model to odd prime qudit dimensions essentially qudit stabilizer quantum mechanics, which is local and non-contextual. So the toy model is not super exotic, rather, it just very computationally weak. 192.76.8.93 (talk) 14:56, 23 March 2023 (UTC)
