Have there been any experiments designed to explicitly test the projection postulate? I mean that part of it that says the measured particle is left in an eigenstate of the measured operator.
The usual devices for measuring particles (photomultipliers, phosphor screens, etc.) don't really allow the postulate to be tested, since the measured particle is absorbed, not re-emitted in a perfect eigenstate. Are there other measurement methods that allow testing the projection postulate?
