I'm slighting confused about the experiments which try to prove that Bell's Inequality is violated. Here's what would satisfy me that Bell's Inequality has been violated: we measure the spin of a photon and its entangled pair at time 1, then at time 2 we change the spin on photon 1 and measure simultaneously the spin of photon 2 at time 2. If it's always the case that if you change the spin of one then the other photon's spin changes simultaneously then that would be good evidence that entanglement is real. Have experimenters been able to do this?(adsbygoogle = window.adsbygoogle || []).push({});
