Titel/Title

Test of the no-signaling principle in CHSH experiments

Sammanfattning/Abstract

The no-signaling principle is an essential feature of quantum theory, as it hides quantum non-locality behind a veil of randomness, and thus keeps it from a direct conflict with special relativity. I will show that testing the fulfilment of this principle is possible with modern tests of Bell’s theorem, in particular with highly efficient “loophole-free” CHSH experiments. I will show that increasing the sample size of event-ready detections in the CHSH experiment recently performed in Delft by Hensen et al. actually leads to an apparent violation of the no-signaling principle, and I will discuss the significance of this result.
