Hi Creon, my theory is different, but there may be more than one way to skin Schrodinger's Cat.
I have not had time to study this one. The guy is not an obvious flake with a Math Dept. Notre Dame address.
Will look at it more closely after a Bay Club workout. I wonder what Stapp thinks?
Is he invoking Aharonov's "weak measurement"?

I am not sure if his "quantum eraser" Fig 2 eq 3 is a correct inference in orthodox quantum theory, i.e. disentangler.

His eq (2) is that photon (2) is in an impure mixed state with non-zero entropy using Fig 1 and that photon (2) is in a pure state with zero entropy in Fig 2. This may be his error. I suspect Stapp will say that in both cases photon 2 is in the impure mixed state without any coherent relative phase as in eq. (3).

For example, can we construct a unitary disentangler U that will act as

U|1+> = |1/>

U|1-> = |1/>

?

Note that <1+|1-> = 0

<1+|U*U|1-> = <1/|1/> = 1 =/= 0

Therefore U is not unitary.

Of course with such a non-unitary "quantum eraser" disentangler we have entanglement signaling here, but that violates QM so I suspect that's his error?
