Sheldon Goldstein does not need any help,
but many experiments actually show, just now,
that Schroedinger's cat is not a paradox about
(our) information (about that weird singlet state)
but a real, physical thing. Please look
http://www.nature.com/nature/fow/
and then click the voice
"Catching Schroedinger's cat".

"Fields in empty space have physical reality;
the medium that supports them does not.
[Quantum] Correlations have physical reality;
that which they correlate does not."
It's not me. It's David Mermin.
