Henry's original statement was to "really test the potential ability of quantum theory's "spooky action at a distance" to beat the speedof light". This is not to be. It may well be that biphotons have an application to financial trades, indeed they are used in quantum cryptography. Perhaps their contribution might be to provide secure and undeniable communication. -- Gene ________________________________ From: Michael Kleber <michael.kleber@gmail.com> To: math-fun <math-fun@mailman.xmission.com> Sent: Sunday, August 9, 2009 5:37:51 PM Subject: Re: [math-fun] Plenty of Room at the Bottom, Part II The mere fact that you can't communicate faster than light doesn't necessarily obviate Henry's point: it seems plausible to me that Bell-type correlations between entangled photon pairs could allow trades that are "simultaneous" (ie outside of each others' speed-of-communication cones) and yet arbitrage a market in a way that is otherwise impossible. Or is there some reason to believe this is not a source of otherwise-impossible profit? --Michael On Sun, Aug 9, 2009 at 8:01 PM, Eugene Salamin <gene_salamin@yahoo.com>wrote:
It's always nice to experimentally test theories whose truth is generally accepted beyond question, for occasional surprises do occur. Nevertheless, all the experimental results thus far are consistent with quantum theory. There is no way, within quantum theory, to communicate faster than light.

People still seem to be running experiments to test non-locality, "non-causality", etc.:

Perhaps the time has come for physicists to really test the potential ability of quantum theory's "spooky action at a distance" to beat the speed of light. I would imagine that one of the large financial trading firms (Goldman Sachs ?) could easily afford to fund such a test. Perhaps they already did... ??
