Disembodiment of Physical Properties by Pre- and Post-Selections

Abstract

The detailed study of disembodiment of physical properties by pre- and post-selection is present. A criterion is given to disembody physical properties for single particle with multiple degrees of freedom. It is shown that the non-commute operators can also be well separated in different paths. We generalize the disembodiment to entangled particles, and found that the disembodiment can happen under special conditions due to the entanglement.
