I would like to make a little poll about the following question.
Let us consider a quantum particle in a box. At a time t1 an impenetrable barrier is inserted into the box, dividing the box in two semiboxes and the wave function of the particle in two disjoined parts. At a subsequent time t2 the semiboxes are open in order to determine in which of them there is the particle. The question is:
Was the particle since the time t1 in the semibox where it has been found at the time t2?
Possible answers:
What do you think?

Was the particle since the time t1 in the semibox where it has been found at the time t2?
Possible answers:
- yes, because the barrier is impenetrable and the particle cannot jump form a semibox to the other.
- no, because the wave function provides the most complete description of the particle, and until t2 it does not contain the which-semibox information
- other...
What do you think?
