 A simpler proof of Bell’s Theorem, also relying upon counterfactual reasoning and based upon a deterministic local theory, is that of Hardy (1993), here presented in Laloë’s (2001) formulation. Consider an ensemble of pairs 1 and 2 of spin\(-\frac{1}{2}\) particles, the spin of 1 measured along directions in the \(xz\)-plane making angles \(a=\theta /2\) and \(a'=0\) with the \(z\)-axis, and angles \(b\) and \(b'\) having analogous significance for 2. The quantum states for particle 1 with spins \(+\frac{1}{2}\) and \(-\frac{1}{2}\) relative to direction \(a'\) are respectively \(\ket{a',+}_1\) and \(\ket{a',-}_1\), and relative to direction \(a\) are respectively
