Photon Entanglement, Bell Inequality Violation, and Energy Interpretation of the Born Rule in Maxwell–Schwartz Field Theory

Abstract

In this paper we study photon entanglement in the framework of Maxwell–Schwartz field theory. The ambient state space is the complex Maxwellian distribution space W=S′(M4,C3), whose elements are fields of the form F=E→+icB→. Polarization is realized as a two-dimensional complex subspace of W, generated by suitable linearly polarized Maxwellian solutions associated with opposite propagation directions. This yields canonical polarization sectors PA and PB, each naturally isomorphic to C2. Within this setting, the Bell singlet state is represented by a non-factorizable tensorial Maxwellian field in PA⊗PB⊂W⊗W. By means of the induced rotated polarization bases, the standard joint probabilities of the photon polarization experiment are recovered exactly, and the correlation law E(a,b)=−cos(2(a−b)) is obtained. Consequently, the usual CHSH value 22 is reproduced in the Maxwell–Schwartz framework. To clarify the meaning of this violation, we first formulate the CHSH inequality in a purely measure-theoretic form, as a theorem about four correlators represented on a single probability space by bounded measurable functions. We then show that the correlators produced by the intrinsic Maxwellian Bell state do not admit such a common representation. The obstruction is structural: the ontic state is a global non-product field configuration, and the four correlations arise from different polarization resolutions of the same tensorial Maxwellian state. A second main result concerns the Born rule. For L2 scalar quantum states in the domain of the Maxwellian correspondence, we prove that the squared Hilbert norm, times the constant ε0, coincides with the electromagnetic energy of the associated field. This leads to an energy interpretation of the Born rule: the Born probability density is identified with the normalized electromagnetic energy density up to an interference term depending on the chosen Maxwell–Schwartz isomorphism, which assumes the role of a quantum context. In the context of the Aspect and collaborators’ experiment, we prove that, on the other hand, the polarization probabilities become energy contributions of the corresponding field components. These results show that photon entanglement, Bell inequality violation, and the Born rule admit a coherent interpretation within Maxwell–Schwartz field theory, where the basic ontological objects are electromagnetic-like fields rather than abstract state vectors.

Spin–1/2 Particle Fields in Maxwell–Schwartz Theory: Dirac–Schwartz Dynamics, Probability Currents and Entanglement

David Carfì

We develop a Maxwell–Schwartz field-theoretic formulation of spin-1/2 quantum systems within the framework of tempered distribution spaces and Schwartz linear algebra. In this approach, the fundamental objects of the theory are Maxwellian fields, namely elements of S′(M4,C3), while scalar quantum states arise as derived projections carrying the spectral structure of the theory. Relativistic dynamics is formulated through square-root Hamiltonian operators defined via spectral calculus. On a distinguished subspace of Maxwellian fields, the curl operator realizes the momentum magnitude operator, allowing a direct correspondence between scalar and vectorial relativistic dynamics. This leads to a Schrödinger-type formulation of relativistic evolution without requiring Dirac’s matrix factorization as a primitive assumption. Spin-1/2 structures emerge naturally from two-component Cartesian configurations of Maxwellian fields. The Pauli algebra is realized as an internal symmetry acting on such pairs, and spin observables correspond to explicit transformations of field components. A first-order Dirac-type dynamics is obtained through operator factorization, yielding a Maxwellian realization of relativistic two-component equations, including the massless Weyl regime. The tensorial structure of the theory provides a natural setting for entanglement. Bell-type correlations are derived intrinsically from Maxwellian field configurations, reproducing the standard quantum predictions and their violation of Bell inequalities. A central result of the present work is the energetic interpretation of quantum probability. The spectral coefficients of a state determine the amplitudes of its Maxwellian realization, whose energy density is quadratic in these amplitudes. The Born rule is thus recovered as a normalized energy distribution law. Moreover, the electromagnetic continuity equation induces a probability continuity equation, with the probability current identified as the normalized Poynting flux. This transport interpretation extends to entangled states, where Bell correlations are interpreted as correlations in the transport of energy across field channels. Finally, the framework is extended to massive Maxwellian fields, where probability currents are expressed through nonlocal spectral kernels associated with square-root Hamiltonians, yielding a unified continuity structure for both massless and massive regimes. These results suggest that spinorial quantum structures, probabilistic interpretation, and quantum correlations may be understood as emerging from the internal organization, spectral structure, and energy transport of Maxwellian fields in the Schwartz distributional setting.

Coincidence Interpretation of the Born Rule: The Two-Photon Bound State as the Physical Origin of \( |\psi|^2 \)

Don T. Froedge

The Born rule assigns probability density \( |\psi|^2 = \psi^* \psi \) to a single wavefunction. It is postulated here that this interpretation, while computationally successful, conflates two physically distinct situations. For a bound state, \( \psi^*\psi \) is not the square of a single wavefunction but the coincidence product of two independent conjugate wavefunctions \( \psi_1\psi_2 \) — one incident, one its counter-propagating conjugate — simultaneously present. Detection of a quantum event requires the coincidence of these two conjugates at the detection point; a single wavefunction alone cannot populate a bound energy state or trigger detection. Stated carefully, the postulate is a bilinear detection law: detection is postulated to depend bilinearly on two conjugate field amplitudes through their product, rather than on an independently squared probability for each field. Under stated hypotheses this law reproduces standard results of quantum mechanics — the double slit interference pattern in the pair-arrival regime, and an invariant composite rest mass for the bound pair — without wavefunction collapse. A complete account of Bell correlations is not claimed: a locally factorizable coincidence model cannot reproduce the quantum correlations for arbitrary analyzer settings, and constructing a CHSH-complete treatment is registered as the central open problem of the interpretation (Section 5). The two-photon electron of Delta-c Mechanics provides the mechanical realization of this postulate: the electron is formed by two conjugate photons in counter-propagating circular orbit, their combined flow density forming a standing wave that is Lorentz invariant by construction. A structural correspondence between the Feynman path-integral hierarchy and this standing-wave construction is proposed in companion work; the exact amplitude mapping remains open. A Thomson scattering experiment capable of distinguishing the coincidence interpretation from standard QM is identified and described in a companion paper.

A Tholonic Structural Reading of Photon Polarization and Entanglement

Jeffrey Milton

Photon polarization is one of the cleanest physical settings in which two-state quantum structure, superposition, interference, and Bell-type entanglement are experimentally realized. This paper asks a narrow structural question: does the tholonic N-D-C geometry contain a native mathematical structure that can represent the polarization degrees of freedom of a photon and the non-factorizable correlations of an entangled photon pair? The answer developed here is qualified but affirmative. The tholonic role space begins with three coordinates, (N, D, C), but its common-mode direction (1,1,1) carries no information about relative role differentiation. Removing that common mode leaves a two-dimensional zero-sum plane V, singled out by the model's own cyclic role symmetry N → D → C → N rather than by convenient axis-dropping. That plane is already implicit in the framework's cube-root-of-unity representation, and a pair of orthogonal directions in it can represent the linear-polarization basis of a photon without declaring the tholonic roles D and C themselves to be orthogonal. For a non-factorizable antisymmetric two-photon state, the corresponding binary observables yield the standard photon-polarization correlation E(a,b) = -cos 2(a-b), with the usual CHSH settings giving |S| = 2√2. Beyond reproducing the standard result, the construction has one feature not visible in the quantum formalism alone: the three roles occupy three fixed directions 120° apart in the relational plane, which as polarization axes form an equiangular trine at 60° spacing. Evaluating CHSH on these native settings, with no angle tuning, gives |S| = 5/2, so the triad's own role directions already violate the classical bound, reaching 88.4% of the Tsirelson bound, while provably falling short of saturation. The construction is not a derivation of quantum mechanics from tholonic first principles. Tensor-product composition and the Born interpretation of squared amplitudes remain quantum postulates, and the full polarization qubit requires complexifying the relational plane. The result is presented as a structural embedding with one quantitative signature, together with a proof, restated from first principles, that no tholonic construction built from two children reading one shared object (fixed, cyclic, or a deterministic parent-to-child pipeline) can exceed the classical CHSH bound of 2.

Entanglement and Bell Inequality Violations from Electromagnetic Mode Competition

Paul Monforton, Sarah Monforton

We extend the electromagnetic mode competition framework to entangled photon pairs. The framework derives the Born rule from classical electromagnetism plus a single empirical input: each emission produces exactly one detection (single-event exclusivity). Here we show that the same postulates, applied to the joint mode structure of spontaneous parametric down-conversion, reproduce the quantum predictions for polarisation-entangled pairs: the sin²(θ₁ − θ₂) coincidence probability and the maximal CHSH violation S = 2√2. We also derive GHZ correlations and the Hong–Ou–Mandel dip. The framework dissolves the mystery of Bell correlations: there are not two photons coordinating across space, but one extended electromagnetic mode undergoing one detection event. Alice and Bob are endpoints of a single structure; their correlation is built in from the moment of emission and enforced by energy conservation. No action at a distance occurs—one detector absorbs the energy, and the shared pool is depleted. Bell's inequality is violated not because of nonlocality, but because Bell's factorisation assumption does not apply to measurements on a single extended object.

Born rule, non-orthogonal projections, and the origin of Bell-CHSH violations

Roberto Pavani

We decompose the Bell-CHSH correlator for the Bell state into a diagonal (classical mixture) contribution and a coherent (off-diagonal) contribution using the density matrix formulation.The diagonal part produces correlations satisfying |S|≤2; the entire enhancement to |S|=2√2 originates from the coherent cross term Re(A₁*A₂), which generates a setting-dependent redistribution of probability among measurement outcomes. This cross term sums to zero over all outcomes (preserving normalisation) but modifies individual coincidence probabilities in a manner that depends on the measurement basis. The coherent contribution is precisely the component that takes Born-rule probabilities outside the class of factorisable probabilities assumed in the derivation of Bell's inequality. We show that this structure is formally parallel to the variance normalisation producing apparent Bell violations in classical coherent-detection systems: in both cases, a setting-dependent operation on coherent amplitudes transforms correlations from |S|≤2 to |S|=2√2.

A Deterministic Maxwellian Model for Bell-CHSH Violation via Synchronized Rotating Electric Field Vectors

Sudeer Punnery

Abstract This paper proposes a local-deterministic completion of quantum entanglement by identifying the instantaneous phase of rotating electric field vectors as the primary hidden variable. We demonstrate that the observed violation of the Bell-CHSH inequality is not a signature of non-locality, but a natural consequence of the Intensity-Phase doubling mechanism inherent in Maxwellian electrodynamics. Through analytical derivation and discrete-time numerical integration, it proves that the correlation of synchronized transverse waves—governed by the quadratic nature of Malus’s Law \(\:\left(\varvec{I}\:\propto\:\:{\varvec{E}}^{2}\right)\)—generates the exact quantum correlation function \(\:E\left(\varDelta\:\theta\:\right)=\:\:Cos(2\varDelta\:\theta\:)\). We resolve the long-standing discrepancy regarding measurement angles by showing that the maximum violation of the CHSH inequality \(\:(S=2\sqrt{2})\) occurs at a physical polarizer setting of \(\:22.5^\circ\:\), which corresponds to a \(\:45^\circ\:\), shift in the internal field phase . By distinguishing between mechanical rotation and field-space geometry, this model saturates the Tsirelson bound while strictly maintaining Einsteinian locality and causality. This framework suggests that the "spooky action" of entanglement is a manifestation of temporal phase-locking between the source and the detector, providing a fully realistic and Maxwellian interpretation of Bell-type statistics.

Coincidence Interpretation of the Born Rule: The Two-Photon Bound State as the Physical Origin of ∣ψ∣2 |\psi|^2 ∣ψ∣2
The Born rule assigns probability density ∣ψ∣2=ψ∗ψ |\psi|^2 = \psi^* \psi ∣ψ∣2=ψ∗ψ to a single wavefunction. It is postulated here that this interpretation, while computationally successful, conflates two physically distinct situations. For a bound state, ψ∗ψ \psi^*\psi ψ∗ψ is not the square of a single wavefunction but the coincidence product of two independent conjugate wavefunctions ψ1ψ2 \psi_1\psi_2 ψ1​ψ2​ — one incident, one its counter-propagating conjugate — simultaneously present.
