Why are you bringing up "Glauber states", Jack?
Just to muddy the waters?

Of course, making imperfect non-strong measurements muddies the waters.

A Glauber state possesses an indefinite photon number.

All entangled states that we know of are Fock states
with a definite photon number.


Really Nick? I think I read there are now entangled laser beams.

In any case, that there may be entangled laser beams does not violate quantum theory as far as I know.

If that could be done, it seems to show a flaw in Stapp's proof and in all the no-cloning no entanglement signaling proofs.

That is, all those proofs at the basis of the black hole information dispute, quantum cryptography etc would be thrown in doubt.

How does this entangled macro-quantum coherent state violate orthodox quantum theory?

|z1)|z'2') + |z2)|z'1')

where

z = sqrt(n)e^i@

So, Nick you agree that orthonormality of the states that are traced over is needed for no-signalling?

Hey Nick what about this?
