SUMMARY:Joseph Henson (Imperial College London) - "Locality Reinstated?"
DESCRIPTION:Monday 21st October; 17:15pm - 18:45pm\nSIGMA\n\nSpeaker: Joseph Henson; Imperial College London\n\nTitle: Locality Reinstated?\n\nAbstract: The assumptions of Bell's theorem were meant by its author to to characterise a lack of any physical superluminal influences.  The ``Quantum non-locality'' he discovered does violence not only to our intuitions; but arguably also to any thoroughgoing attempts to apply causal explanation in QM. \n\nIt is natural to wonder if there is a better way to characterise locality (= lack of superluminal influence) that is consistent with QM; thereby resolving an apparent contradiction by discarding some conceptual ``excess baggage.''  However; in order to do this we must be careful to preserve what is essential in the idea of locality.  In this talk; I will describe a particular view of  Bell's condition; and point out a (hopefully uncontroversial) list of conditions that any reinstated ``locality'' should obey.  I will then apply these conditions to a number of candidates in the literature; including some treatments of locality in many-worlds QM; Howard's non-separability and ``super-determinism;'' and find them to be violated.  Finally I will speculate about the extent to which a useful concept of locality textit{can} be preserved in QM. \n\nVenue: LAK 2.06
