As described in the section above, measuring the spin about the horizontal axis can allow an atom that was spun up to spin down: measuring its spin about the horizontal axis collapses its wave function into one of the eigenstates of this measurement, which means it is no longer in an eigenstate of spin about the vertical axis, so can take either value.

Pengukuran spin di sekitar sumbu horizontal dapat memungkinkan atom yang tadinya spin atas menjadi spin bawah: pengukuran spin di sekitar sumbu horizontal meniadakan fungsi gelombangnya menjadi salah satu eigenstate pengukuran ini, yang berarti tidak lagi berada pada eigenstate spin di sekitar sumbu vertikal, sehingga nilainya bisa lain.
