- "In order for the evolution to be unitary, we must have <a,e,+|a,o,+> = 0."
-
- Why? Both |a,e,+> and |a,o,+> are identical in spin space and they both
- evolve to |h>. In fact
-
- <a,e,+|a.o.+> = e^ix
-
- Ramsay is confused. The proper orthogonality relations are:
-
- <a,e,+|a,e,-> = 0
-
- <a,o,+|a,o,-> = 0
-
- I will comment on the rest of Ramsay's reamrks in another posting.
