Anomaly of non-locality and entanglement in teaching quantum
... Summing up, we have to clarify concepts even in the first approach to QIT in QM: entanglement is to be related to the possibility or not of having a state written as a convex sum of a tensor product of individual parties, whereas non-locality is related to the impossibility of LVM to describe or rep ...
