Question: On checking Bell's inequality Eq. with mutually parallel polarizationentangled photons,
a. Is it violated using polarizers A vertical, B at 22.5?, and C at 22.5? from B and 45? from A?
b. Is it violated for A vertical, B at 50?, and C at 50? from B and 100? from A?
c. If A is vertical, B forms an angle θ with A, and C forms an angle θ with B and 2θ with A, find the values of θ for which the inequality is violated. The inequalities are not always violated by an indeterministic quantum description, but they are never violated by a deterministic description.
N(A, B¯) + N(B, C¯) ≥ N(A, C¯) a Bell inequality
