Paper T4: Entanglement and Decoherence via Triadic Spin

This paper develops a structural interpretation of quantum entanglement and decoherence based on Holosphere Theory. In this model, particles are composed of three dark bosons orbiting a vacancy defect in a discrete lattice of rotating holospheres. Among the three, only one boson aligns with the long range coherence axis and maintains entanglement across spatial separation. The other two occupy tangential orbital modes that are unstable under lattice strain and undergo decoherence when misaligned. Entanglement is redefined as shared angular phase alignment along the lattice coherence axis, while decoherence arises from orbital misalignment and redistribution of angular strain. Collapse is described as a deterministic diffusion of strain through the lattice rather than an indeterminate wavefunction event. This framework resolves the measurement problem, delayed choice paradoxes, and Bell type correlations without invoking non locality. The theory predicts that at decoherence the two tangential bosons are forced into geometric dark node zones of SU(2)/S3, where coherence is completely suppressed. Only the radial boson remains in the coherence corridor. This asymmetry provides a falsifiable explanation of why entanglement is fragile in some directions and robust in others. Observable predictions include orientation dependent entanglement fidelity, decoherence plateaus with temperature, and complete suppression of correlations at specific dark node phases. By grounding quantum behavior in the discrete geometry of holosphere triplets, this work offers a realist and testable alternative to standard interpretations of quantum mechanics.
