Symmetric and Asymmetric Models for Atomic Cascade Experiments
It is pointed out elsewhere in this book (see, for example, the chapters of Santos and of Marshall) that the evidence from optical tests of the Bell inequalities cannot be used to support any claim(1,2) that quantum nonlocality is an experimentally established phenomenon. Such claims have been based on some confusion between the two principal types of Bell inequality: homogeneous and inhomogeneous. The first type of inequality is satisfied only in those local realist theories satisfying some kind of auxiliary hypotheses, while the second must be satisfied in all local realist theories. This was already clear in the article of Clauser and Horne,(3) but it is only relatively recently that any serious study has been made of those local realist theories which do not satisfy the auxiliary hypotheses.
