Hello I'm a bit confused for the part 2 where we have to redo a), b), c), d) using phi_1. I obtain the exact same result as for the part 1 using phi_0. Do I need to rewrite everything or can I just write I find the same results ?
Hi, If you find thee excat same results for psi_0 and psi_1 then you have it wrong... Psi_0 is an entangled Bell state and teh chsh inequ is violated. The reduced density matrxi of Psi_1 is a mixed state (see some previous hmw in fact !) so the inequality is not violated.
