Quantum Source Transition Theory

Erik Krager

This preprint introduces Quantum Source Transition Theory (QSTT), a source-side framework for interpreting the relationship between quantum probability structure, physical record formation, and gravitational source behavior. This is a preliminary attempt to try and bridge QM with GR using a quantum probability source structure. The central proposal is that the gravitational source term should be treated as a transition structure rather than a purely classical object. QSTT expresses this through an effective stress-energy form: T_eff = T_classical + T_Psi + T_C In this expression, T_classical represents conventional recorded or classical matter-energy, T_Psi represents coherent probability-phase source structure, and T_C represents transition stress-energy associated with physical record formation. The paper develops a record-based interpretation of the quantum-to-classical transition using branch distinguishability, record strength, and record-formation rates. It also outlines how QSTT may be tested or constrained through mesoscopic gravity experiments such as QGEM/BMV-style proposals, where the key question is whether gravitational phase accumulation can occur before durable which-branch records are formed. A preliminary weak-field closure branch is also included, along with supporting comparison material against MOND-style phenomenology. These results are presented as an initial phenomenological test direction rather than as the central foundation of the framework. This v1.0 preprint is intended as a foundation release: it defines the core source-side structure, establishes the physical-record terminology, identifies testable regimes, and provides companion data and plots for early weak-field exploration.

State Locality Theory: A Phenomenological Framework for the Quantum–Classical Transition

Mikhail Bespoyasov

This work introduces the State Locality Theory (SLT), a phenomenological framework describing the quantum–classical transition through a single continuous parameter of locality. The theory proposes that quantum behavior arises from low-locality states, while classical behavior emerges as locality increases, with decoherence interpreted as a natural consequence of this transition. SLT provides a unified explanation for interference visibility, gravitational amplification of locality, and the suppression of nonlocal correlations in macroscopic systems. The framework is formulated without modifying quantum mechanics, instead offering a phenomenological layer that clarifies how classicality emerges from quantum foundations. The theory outlines testable predictions, discusses implications for measurement, and proposes a structured approach for extending SLT toward a full dynamical formulation.
