A single particle is prepared in a (weird) superposition.

The superposition consists in being in three boxes.

The initial state is |psi_1>

|psi_1> = 3 ^ (-1/2) ( |A> + |B> + |C> )

and the final state is |psi_2>

|psi_2> = 3 ^ (-1/2) ( |A> + |B> - |C> )

where A, B and C are the three boxes.

If you search, in the intermediate time, in the box A

you'll find the particle. Otherwise the state would be

|psi_huh> = 2 ^ (-1/2) ( |B> + |C> ) which is forbidden

being orthogonal to the final state.

If you search, in intermediate time, in the box B

you'll find the particle. Otherwise the state would be

|psi_hoh> = 2 ^ (-1/2) ( |A> + |C> ) which is forbidden

being orthogonal to the final state.

Then the single particle is in the box A (searching in A)

and in the box B (searching in B).

What about searching in A *and* B? I don't know.

And it's too late now. And QM is a nasty trick.
