- Well John Baez you don't like "super"? How about superposition?
- superstring? superfluid? superconductivity? superstition? supercilious?
-
- Are you saying that Princeton University supports crackpot science in their
- PEAR laboratory headed by Dean of Engineering, Robert Jahn with money from
- Mc Donnell Douglas and Federal Intelligence Community?
-
- But what about the substantive issue. Parallel slit kets seem to work as
- well as perpendicular ones. If not, why not?
-
- Linearity seems to contradict local dynamics. Thus, a polarizing beam
- splitter makes two beams with no common support in space, so that
-
- |i> = |e+><e+|i> + |o-><o-|i>
-
- and for some times t, at least, when <x|e+> not zero then <x|o-> is zero
- and vice versa. There is no x such that both <x|e+> and <x|o-> are non-
- zero.
-
- A half-wave plate (1/2) acts on o-beam. It acts locally. There is no way it
- can affect the separated e-beam. The plate is represented by a unitary
- operator U(1/2) in the Hilbert sub-space in which |e+> and |o-> form an
- orthonormal basis. <e+|o-> = 0 etc. The locality of the photon-electron
- scattering in region of 1/2-plate means
-
- U(1/2)|o-> = |o+>
-
- for the time being, let's agree with Ramsay that <e+|o+> = 0 . There is
- still a paradox.
-
- Local dynamics demands that
-
- U(1/2)|i> = |e+><e+|i> + U(1/2)|o-><o-|i> = |e+><e+|i> + |o+><o-|i>
-
- Linearity demands the contradictory
-
- U(1/2)|i> = U(1/2)|e+><e+|i> + U(1/2)|o-><o-|i> = |e-><e+|i> + |o+><o-|i>
-
- but we would be surprised if by putting a 1/2 plate in the o-beam we also
- rotated the plane of polarization of the far away e-beam by 90 degrees.
- This would be a new kind of dynamical nonlocality different from
- kinematical connection nonlocality tested by Bell's inequality.
