I bet that circular crest's diameter is SNAT.

This nicely illustrates the geometry inversion at the unit boundary.

If the crest represents SNAT then the inner cone represents the Time

Region and the negative probability in the center may have a rational

explanation. My first two guesses are (1) it is either a Time Region

artifact or (2) the plot needs to be redone taking into account the

counter space geometry of the Time Region.

If the probabilities under the plot were integrated, you would expect the

sum to be one. I wonder if they did that?

I've always treated it as a radius of SNAT; but I agree. The transition from positive to negative probability does indicate that it is leaving "space".

Given that counterspace is "negative space", the negative probability that is indicated in the article becomes a positive probability in counterspace.

The lead author of the paper, Dr. Alex Lvovsky, is now at the

University of Calgary leading the Quantum Information Technology

program whose home page is:

http://qis.ucalgary.ca/quantech/index.html

I found the site quite interesting.

The complete PDF file of the original 4 page published

scientific article from Physical Review Letters Vol. 87 Number 5,

30 July 2001 is posted at:

A slightly less technical statement is at:

http://qis.ucalgary.ca/quantech/fock.html

A tantalizing statement, "... the nonlocal single photon is one

of those rare cases in physics when the experimental work is

ahead of theoretical" is on web page:

http://qis.ucalgary.ca/quantech/nonlocality.html

I would restate that as, "Neither quantum mechanical theories

nor classical theories give adequate explanations for the

experimental data."

Is this an opportunity for someone in the RS world who can

provide a better theoretical explanation? A working knowledge

of quantum mechanical vocabulary will be required, because that

is the vocabulary of the technical papers.
