The Usenet sci.physics FAQ has a good introduction on the EPR paradox,
Bell's inequality, entanglement, etc. See:
The FAQ seems to say that the jury is still out on this whole subject,
theoretically as well as experimentally. Doesn't sound to me as if FTL,
action at a distance is a proven reality. But then I haven't read Nick
Herbert's book.

Guess I missed the IBM article; do you have a reference?
