Abstract Einstein’s “spooky action at a distance” names a correlation that no local mechanism can produce. This article turns that observation into an audit instrument for artificial intelligence. Two AI agents that share training data, weights or random seeds but cannot communicate are local systems in Bell’s sense, so their behaviour in a Clauser–Horne–Shimony–Holt (CHSH) game is bounded by S ≤ 2 whatever their architecture; a significant excess identifies a covert channel without modelling the agents. The instrument is tested in three computational experiments with known ground truth. First, 135 trained pairs of neural agents (three widths, three latent dimensions, two objectives) never exceed the bound (maximum S = 2.0000), including pairs trained to imitate the correlations of an entangled singlet. Second, opening a one-bit channel with probability p moves the learned CHSH value onto the theoretical optimum 2 + 2 p (mean absolute deviation 0.0016 across 220 runs); any leak below p ≈ 0.414 produces values indistinguishable in S from quantum entanglement. Third, as a finite-sample test the audit keeps its nominal size against honest but strongly correlated agents (rejection 4.4% and 4.3%), whereas a conventional dependence test flags the same agents in 100.0% of audits; detecting a 5% leak with 80% power needs about 7,375 rounds and a 1% leak about 185,120. The decisive weakness lies with the auditor: with predictable settings (a low-order bit of a linear congruential generator, a fixed rotation or a reused seed), agents with zero communication reach S ≈ 4 and trigger false alarms in 100% of audits, while cryptographic and freshly seeded generators restore the nominal error rate. The bridge to algorithmic collusion and multi-agent AI governance is stated as a formal analogy and a hypothesis for field testing, not as a finding about deployed systems.

PENDING QUALITY AUDIT (2026-08). The file is restricted while this record is reviewed as part of a systematic audit of the author's corpus. It has not yet been assessed. Metadata and DOI remain public, and access can be requested. Einstein's "spooky action at a distance" conflates two distinct phenomena: statistical non-locality (correlations that violate Bell inequalities) and computational non-classicality (correlations that cannot be efficiently simulated classically). These are not the same thing. This paper shows that quantum non-classicality has two independent components: entanglement topology (which parties are correlated, measured by concurrence or entanglement entropy) and magic valence (what kind of non-classical correlations they share, measured by the Fano orbit label {p_L}). The Bell/CHSH framework captures the first component but not the second. The Fano Line Verification Game captures both. Crucially: a maximally entangled Bell pair |Φ⁺⟩ = (|00⟩ + |11⟩)/√2 is a stabiliser state — it has orbit label L=0 and zero magic. It violates Bell inequalities but is efficiently classically simulable by the Gottesman-Knill theorem. Computationally meaningful "spookiness" — the kind that enables quantum advantage — requires magic (non-zero orbit valence), not just entanglement. The Spacelike Associator Paradox, Hardy's Paradox, and the Fano Monogamy Paradox are revisited through this two-component lens. Each is sharpened: the ORBIT opcode provides a concrete experimental test distinguishing entanglement non-locality from magic non-locality in a single 7-measurement protocol. Einstein's objection to spooky action is reinterpreted: he objected to entanglement non-locality alone — the second component, magic non-locality, was not accessible to him.

Bell nonlocality is the experimentally testable incompatibility between quantum correlations and explanations based on local hidden variables. Its significance now extends beyond the foundations of quantum mechanics: a Bell-inequality violation can certify entanglement, randomness, measurement incompatibility, and cryptographic security without requiring a detailed model of the devices producing the observed data. This article develops the mathematical structure of Bell experiments and explains its role in device-independent quantum information. Conditional probability distributions are classified into local, quantum, and no-signalling sets; the Clauser-Horne-Shimony-Holt inequality is derived, and its classical, quantum, and algebraic limits are distinguished. Tsirelson’s bound is obtained from the CHSH operator, while Popescu-Rohrlich correlations demonstrate that no-signalling alone does not identify the quantum set. The relation between entanglement and nonlocality is examined through local entangled states, hidden nonlocality, and activation. Nonlocal games, semidefinite relaxations, self-testing, certified randomness, and device-independent quantum key distribution are treated as operational consequences of Bell violation. Particular attention is given to entropy accumulation, finite-data security, loophole-free experiments, and the limitations of device independence. Bell nonlocality emerges as both a foundational separation between classical and quantum causal models and a quantitative resource for cryptographic and informational tasks.
This work provides quantitative tests of the extent of violation of two inequalities applicable to qubits coupled into Bell states, using IBM's publicly accessible quantum computers. Violations of the inequalities are well established. Our purpose is not to test the inequalities, but rather to determine how well quantum mechanical predictions can be reproduced on quantum computers, given their current fault rates. We present results for the spin projections of two entangled qubits, along three axes A, B, and C, with a fixed angle θ between A and B and a range of angles θ' between B and C. For any classical object that can be characterized by three observables with two possible values, inequalities govern relationships among the probabilities of outcomes for the observables, taken pairwise. From set theory, these inequalities must be satisfied by all such classical objects; but quantum systems may violate the inequalities. We have detected clear-cut violations of one inequality in runs on IBM's publicly accessible quantum computers. The Clauser-Horne-Shimony-Holt (CHSH) inequality governs a linear combination S of expectation values of products of spin projections, taken pairwise. Finding S > 2 rules out local, hidden variable theories for entangled quantum systems. We obtained values of S greater than 2 in our runs prior to error mitigation. To reduce the quantitative errors, we used a modification of the error-mitigation procedure in the IBM documentation. We prepared a pair of qubits in the state |00〉, found the probabilities to observe the states |00〉, |01〉, |10〉, and |11〉 in multiple runs, and used that information to construct the first column of an error matrix M. We repeated this procedure for states prepared as |01〉, |10〉, and |11〉 to construct the full matrix M, whose inverse is the filtering matrix. After applying filtering matrices to our averaged outcomes, we have found good quantitative agreement between the quantum computer output and the quantum mechanical predictions for the extent of violation of both inequalities as functions of θ'.
CORRECTION NOTICE — This version supersedes v1 (DOI: 10.5281/zenodo.20499330), which used misleading certificate names BELL-PASS and BELL-CLASSICAL. See ERRATA.md for full details. NOT A PHYSICAL BELL TEST: The CHSH framework in this paper is repurposed as a mathematical correlation classifier for AI feature matrices — NOT as a test of quantum mechanics in AI systems. AI systems do not satisfy the locality and measurement independence conditions required for genuine Bell tests. The CHSH-INSPIRED-CORRELATION-AUDIT certificates are correlation pattern labels only, not evidence of quantum entanglement.

A correlation inequality is derived from local realism and a supplementary assumption. Unlike Clauser-Horne (CH) inequality [or Clauser-Horne-Shimony-Holt (CHSH) inequality] which is violated by quantum mechanics by a factor of 2, this inequality is violated by a factor of 1.5. Thus the magnitude of violation of this inequality is approximately 20.7% larger than the magnitude of violation of previous inequalities. Moreover, unlike CH (or CHSH) inequality which requires the measurement of five detection probabilities, the present inequality requires the measurement of only two detection probabilities. This inequality can therefore be used to test locality more simply than CH or CHSH inequality.
It is well-known that in certain scenarios weakly entangled states can generate stronger nonlocal effects than their maximally entangled counterparts. In this paper, we consider violations of the Clauser-Horne-Shimony-Holt (CHSH) inequality when one party has inefficient detectors, a scenario known as an asymmetric Bell experiment. For any fixed detection efficiency, we derive a simple upper bound on the entanglement needed to violate the inequality by more than some specified amount $\ensuremath{\kappa}\ensuremath{\ge}0$. When $\ensuremath{\kappa}=0$, the amount of entanglement in all states violating the inequality goes to zero as the detection efficiency approaches 50 from above. We finally consider the scenario in which detection inefficiency arises for only one choice of local measurement. In this case, it is shown that the CHSH inequality can always be violated for any nonzero detection efficiency and any choice of noncommuting measurements.
