Device-independent witness of arbitrary-dimensional quantum systems employing binary-outcome measurements
Device-independent witness of arbitrary-dimensional quantum systems employing binary-outcome measurements
Device-independent dimension witnesses (DWs) are a remarkable way to test the dimension of a quantum system in a prepare-and-measure scenario imposing minimal assumptions on the internal features of the devices. However, as the dimension increases, the major obstacle in the realization of DWs arises due to the requirement of many-outcome …
