Replication of the CHSH experiment (Clauser et al. 1969) — prepare Bell states, measure correlations at four angle pairs, and verify S > 2 violates the classical bound.
Replication of Clauser, Horne, Shimony, Holt (1969) — the most fundamental test that quantum mechanics works.
Prepare a Bell state |Φ+⟩ = (|00⟩ + |11⟩)/√2, measure correlations at four pairs of angles, and compute the CHSH parameter S. Classical theories predict |S| ≤ 2; quantum mechanics predicts S = 2√2 ≈ 2.828.
S ≈ 2.83 — violates the classical bound by more than 40%.

The four correlator measurements are independent and run in parallel when executed through Temporal.
