Do particles communicate backward in time?

John Cramer, who writes the “Alternate View” columns for Analog Science Fiction and Fact (one of the “Big Three” science fiction magazines, the others being Asimov’s Science Fiction and The Magazine of Fantasy & Science Fiction) has drummed up enough private funding to proceed with an experiment to test his theory of “quantum retrocausality”:

The notion, absurdly reduced, is this: Entangled photons seem to be able to affect each other no matter how widely separated in time or space, the so-called Einstein-Podolsky-Rosen paradox that illuminates the bizarre nature of quantum mechanics. Do a measurement on one and it has an immediate effect on the other. Cramer is testing whether this ’spooky action at a distance’ is the result of communications that move backwards and forwards in time.

That quote is from the Centauri Dreams blog, which is where I discovered that the scientist in question is the Analog columnist, something I hadn’t twigged to before.

Here’s a straight news story from the Seattle Post-Intelligencer.
