Mark Broom, Talel Naccache, Emmanuel M. Pothos +2
Scientific inquiry seeks causal explanations of observed phenomena. The Bell experiment provides a paradigmatic case, revealing correlations between spatially separated systems tha…

Comparing the cost of violating causal assumptions in Bell experiments: locality, free choice and arrow-of-time
Pawel Blasiak, Christoph Gallus
The causal modelling of Bell experiments relies on three fundamental assumptions: locality, freedom of choice, and arrow-of-time. It turns out that nature violates Bell inequalitie…

Identical particles as a genuine non-local resource
Pawel Blasiak, Marcin Markiewicz
All particles of the same type are indistinguishable, according to a fundamental quantum principle. This entails a description of many-particle states using symmetrised or anti-sym…
