Some people think they have a poltergeist in their attic, some say they’ve seen ghosts on dark nights – I have John Stewart Bell. The physicist’s research and his tremendous legacy have been haunting ...

An international team has confirmed that large quantum systems really do obey quantum mechanics. Using Bell’s test across 73 qubits, they proved the presence of genuine quantum correlations that can’t ...

However, conclusions about the nature of reality based on quantum theory, particularly those from Bell’s theorem, typically depend on an implicit assumption of standard four-dimensional spacetime and ...
