Bell’s theorem for temporal order
Time has a fundamentally different character in quantum mechanics and in general relativity. Here, the authors consider a thought experiment where a massive body in a spatial superposition leads to entanglement of temporal orders between time-like events, resulting in a violation of a Bell-type ineq...

Time has a fundamentally different character in quantum mechanics and in general relativity. Here, the authors consider a thought experiment where a massive body in a spatial superposition leads to entanglement of temporal orders between time-like events, resulting in a violation of a Bell-type inequality. |
