Estimations of Bell expressions Id.
The values of the Bell expressions are estimated by approach measuring the density matrix ρΦ(d)27. The results based on this approach agrees with the measured values shown in Fig. 4. Violation of the Bell-CGLMP inequality [Eq. (1)] is shown for large d for both of the two approaches overcoming the limit of Id (2) predicted in LRT. (I2 = 2.75 ± 0.03, I4 = 2.77 ± 0.05, I8 = 2.76 ± 0.08 and I16 = 2.73 ± 0.10).
