Quantum clarification

Nicolas Courtemanche, Claude Crépeau

In the paper “Super-Quantum Correlations: A Necessary Clarification” by Uzan [1], it is suggested that stronger than quantum (or supra-quantum) correlations are not possible. The main point of Uzan’s argumentation is the belief that the intuitive definition of No-Signalling (NS) is different from the statistical definition of No-Signalling (NSstat), and that situations exist where NSstat is respected while NS isn’t. In this paper we show why these definitions are one and the same, and where the example from the original paper breaks down. We provide a broader context to help the reader understand intuitively the situation.

This is an extension of my previous pre print, in which it will be again once iterated the clarifications of the many dimensions interpretation. This article was published on OSF preprints, titled ‘Additional information and clarifications surrounding the Many dimensions interpretation of quantum mechanics’ (https://osf.io/xq8jm). There will be information included from that article, as well as an extension of a new thought experiment in quantum mechanics, which will reach various philosophical implications. This will not be fully developed and there are plans for a more refined version.

This paper proposes a necessary clarification about the problematic of super-quantum correlations, whose mainstream debate relies on an incorrect, statistical interpretation of the no-signaling condition. The no-signaling condition is an informational constraint that limits the strength of non-local correlations to the Tsirelson bound.
