Is it correct to assume that once a system becomes entangled with another system, regardless of how it happens the two systems form a relationship analogous to the singlet state where non-locality applies between the two systems now considered non-separable? That is, does entanglement necessarily imply non-locality, a point IIUC which LC made earlier on this thread? AG > > Consider a scattering interaction between two billiard balls.
