- A paradox in standard quantum mechanics?
-
- Suppose we have a coherent superposition
-
- |i> = |1><1|i> + |2><2|i>
-
- <1|2> = 0
-
- <1|1> = <2|2> = <i|i> = 1
-
- but suppose |1> and |2> have no common support in x-space. Thus, whenever
- <x|1> not zero <x|2> is zero and vice versa. For example the e and o beams
- from a calcite doubly refracting crystal.
-
- Noe suppose we put an instrument in the path of the |1> ket but not the |2>
- ket. The action of the instrument should be represented by a local unitary
- operator U. But that operator only acts locally on |1> and not on |2> - yet
- |1> and |2> are an orthonormal basis spanning same vector space.
-
- Thus, we have a contradiction between locality and linearity of the
- operator on the vector space. Physicaly, locality means that U only acts on
- |1> not on |2> so that dynamical locality requires:
-
- U|i> = U{|1><1|i> + |2><2|i>} ={U|1><1|i> + |2><2|i>}
-
- In contrast mathematical linearity requires:
-
- U|i> = U{|1><1|i> + |2><2|i>} ={U|1><1|i> + U|2><2|i>}
-
- This very fundamental paradox is at the root of the debate between me and
- Gallis,Baez,Ramsay et-al.
-
- Well gentlemen?
