... mechanics is based on operators acting on vectors in some vector space. A wavefunction ψ corresponds to some abstract vector |ψi, a ket vector. |ψi represents the state of some physical system described by the vector space. If |ψ1 i and |ψ2 i are ket vectors then |ψi = a1 |ψ1 i + a2 |ψ2 i is a possi ...

It is not completely obvious, but this non-switching/switching classification serves to classify the mutually deformable classes of histories ...

Therefore, particle 2 is bound to move subsequently downward independently of its initial up-set position. And so the outcome of the second measurement, on the right, will be z2 with certainty, just as ...
