Interference of macroscopic superpositions
arXiv:quant-ph/0007117
Abstract
We propose a simple experimental procedure based on the Elitzur-Vaidman scheme to test the persistence of macroscopic superpositions. We conjecture that its implementation will reveal the persistence of superpositions of macroscopic objects in the absence of a direct act of observation.
