Bell inequality for quNits with binary measurements

Publication date2003

We present a generalized Bell inequality for two entangled quNits. On one quNit the choice is between two standard von Neumann measurements, whereas for the other quNit there are N2 different binary measurements. These binary measurements are related to the intermediate states known from eavesdropping in quantum cryptography. The maximum violation by √N is reached for the maximally entangled state. Moreover, for N=2 it coincides with the familiar CHSH-inequality
