Abstract

In this work we show that in double-slit experiment properties incompatible with Which Slit property can be detected without erasing the knowledge of which slit each particle passes through and without affecting the point of impact on the final screen. A systematic procedure to find these particular properties is provided. A thought experiment which realizes this detection is proposed.
