A Tsirelson bound is an upper limit to quantum mechanical correlations between distant events. Given that quantum mechanics violates Bell inequalities (i.e., it cannot be described by a local hidden-variable theory ), a natural question to ask is how large can the violation be.
Aug 4, 2018 · In this Insight, I will answer Wheeler’s question per its counterpart in quantum information theory (QIT), “How come the Tsirelson bound?” Let me start by explaining the Tsirelson bound and its relationship to the Bell inequality, then it will be obvious what that has to do with Wheeler’s question, “How Come the Quantum?”
Cirel'son's inequality. Cirel'son raised the question whether quantum theory imposed an upper limit to correlations between distant events (a limit which would of course be higher than the classical one, given by Bell's inequality). (Peres, Sect. 6-5 on p. 185.) Though, I just answered the question.
Oct 3, 2017 · As its well known, quantum correlations break Bell's inequalities only to a certain limit called the Tsirelson's bound. The bound was written for the CHSH inequality. My question is what is the Tsirelson bound for the original case that Bell dealt with in his article, and how it is proven.
Jun 8, 2024 · Tsirelson’s bound: How Nature limits non-locality Spooky action at a distance”, or more formally non-locality, is one of the (or maybe even the ) most intriguing and defining aspects of quantum physics.
A Tsirelson bound is an upper limit to quantum mechanical correlations between distant events. Given that quantum mechanics is non-local, i.e., that quantum mechanical correlations violate Bell inequalities, a natural question to ask is "how non-local can quantum mechanics be?", or, more precisely, by how much can the Bell inequality be violated.
