Experimental verification of wave packet collapse using fourth-order interference

Kazufumi Sakai


The concept of wave packet collapse is the most interesting and difficult to understand assumption of quantum mechanics and it remains an unresolved issue. Therefore, it is necessary to carefully examine its principle and process experimentally. We fabricated a new fourth-order interference apparatus capable of verifying the collapse of a wave packet. Contrary to expectation, a “collapse” was not observed in our experiment.
