Abstract

fetched live from OpenAlex

Nonlocality is a quintessential signature of nonclassical behaviour and a resource for quantum advantages in communication and computation.The paradoxical correlations witnessed by strong nonlocality undergird the standard probabilistic form of nonlocality and provide optimal advantages in numerous informational tasks.Three-qubit systems are the simplest ones that admit strong nonlocality.Abramsky et al. (TQC, 2017) established the existence of an infinite family of three-qubit paradoxes, beyond the well-known GHZ paradox, which exhibited a novel conditional structure.In this work, we introduce several new infinite families of three-qubit paradoxes and articulate a detailed roadmap towards the complete classification of all three-qubit nonlocality paradoxes.In particular, we prove that our paradoxes exhaust all those satisfying reasonable regularity conditions.We give an example of a highly exotic paradox and place constraints on the search for new exotic paradoxes.We conjecture that all paradoxes must involve states from a one-parameter family and provide significant evidence in support of this conjecture.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
