Our result suggests that giving up the concept of=20 locality is not sufficient to be consistent with quantum=20 experiments, unless certain intuitive features of realism=20 are abandoned." ______________ Take 1: (relatively) Recent experiments indicate that the=20 strong intuitive impression that reality exists prior to a=20 measurement being made is an illusion. Cut ... Take 2: Nothing exists as perceived until we perceive it. or Nothing exists as measured until it is=20 measured. Cut ... Take 3: Please do adjust your sets to make reality=20 occur. To be valid QM (Quantum Mechanics) requires that one or both=20 of the following is true: - Reality is created by the measurement process - "Action at a distance" is valid - whereby objects at a=20 substantial distance are instantaneously linked (aka=20 Einsteins "Spooky action" which he denied existed.) In the prior tests of "Bell's inequality" action at a=20 distance was shown true. Now, it seems, the unreality of reality has also been=20 demonstrated. Enjoy! :-) ________________________________ While the ability to produce and measure "Quantum=20 entanglement" is now well accepted, the implications of this=20 were not clear enough to properly shake the foundations of=20 common sense. (QM does this well enough already all by=20 itself but people have managed to ignore it so far). Now a PhD student and colleagues have carried out=20 experiments which demonstrate that reality aint so. Good write up http://www.seedmagazine.com/news/2008/06/the_reality_tests_1.php?page= =3Dall&p=3Dy _________ A 2007 paper from the man - http://www.nature.com/nature/journal/v446/n7138/abs/nature05677.h= tml Simon Gr=F6blacher1,2, Tomasz Paterek3,4, Rainer Kaltenbaek1,=20 aslav Brukner1,2, Marek ukowski1,3, Markus Aspelmeyer1,2 &=20 Anton Zeilinger1,2 Nature 446, 871-875 (19 April 2007) |=20 doi:10.1038/nature05677; Received 22 December 2006; Accepted=20 13 February 2007 Most working scientists hold fast to the concept of=20 'realism'=97a viewpoint according to which an external reality=20 exists independent of observation. But quantum physics has=20 shattered some of our cornerstone beliefs. According to=20 Bell's theorem, any theory that is based on the joint=20 assumption of realism and locality (meaning that local=20 events cannot be affected by actions in space-like separated=20 regions) is at variance with certain quantum predictions.=20 Experiments with entangled pairs of particles have amply=20 confirmed these quantum predictions, thus rendering local=20 realistic theories untenable. Maintaining realism as a=20 fundamental concept would therefore necessitate the=20 introduction of 'spooky' actions that defy locality. Here we=20 show by both theory and experiment that a broad and rather=20 reasonable class of such non-local realistic theories is=20 incompatible with experimentally observable quantum=20 correlations. In the experiment, we measure previously=20 untested correlations between two entangled photons, and=20 show that these correlations violate an inequality proposed=20 by Leggett for non-local realistic theories. Our result=20 suggests that giving up the concept of locality is not=20 sufficient to be consistent with quantum experiments, unless=20 certain intuitive features of realism are abandoned. --Boundary_(ID_axqapKftW+ObTe6GlrCKog) Content-type: image/gif; name=glyph.gif Content-disposition: attachment; filename=glyph.gif Content-Location: http://www.nature.com/__chars/_c/special/caron/black/med/base/glyph.gif Content-Transfer-Encoding: base64 R0lGODlhCQAOAMQAAP///wAAAHh4eF9fX83NzYCAgOXl5Y6OjlhYWJiYmPz8/NHR0WxsbPr6+nJy cltbW97e3uvr62pqaggICKenp/v7+wAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACwAAAAA CQAOAAAFMiAgBoBEiiIRBASKHocrUmuQiI0wRYZzCgjZqCAEBIhCwaNoGAQUFcgJsHCuGMWs1hUC ADs= --Boundary_(ID_axqapKftW+ObTe6GlrCKog) Content-type: image/gif; name=glyph.gif Content-disposition: attachment; filename=glyph.gif Content-Location: http://www.nature.com/__chars/_z/special/dot/black/med/base/glyph.gif Content-Transfer-Encoding: base64 R0lGODlhCwAWAJH/AMDAwKampgAAAAAAACH5BAEAAAAALAAAAAALABYAQAIfhB+nJusPhJxqWohN ws11loVQIGzi8X2LunLVCcdxAQA7 --Boundary_(ID_axqapKftW+ObTe6GlrCKog)-- --===============1065233690== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Disposition: inline Content-Transfer-Encoding: 7bit -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --===============1065233690==--
