In this work we theoretically show that in a double‐slit experiment it is possible the simultaneous detection of properties incompatible with which‐slit property and with each other, together with the measurement of the position of the final impact point. General conditions for the existence of solutions are singled out and families of solutions are provided.

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.
