Defined key components: Complete Relational Configuration (CRC) and Limited Observational Reference Frame (L-ORF).
Maintained standard quantum mechanics formalism while offering a new perspective on measurement outcomes.
Identified how definite outcomes in quantum systems emerge from relational structures in spacetime.
Demonstrated that quantum probabilities stem from limitations in observation rather than pure randomness.
Provided insights into the mathematical formalism of quantum mechanics, linking structure to measurement.

Abstract

TitleStructural Observability: A Framework for Quantum Measurement and Probability This paper proposes the Structural Observability (SO) framework for interpreting quantum measurement and probability. The framework distinguishes between a Complete Relational Configuration (CRC), representing the full relational structure of reality, and the Limited Observational Reference Frame (L-ORF), representing the restricted observational perspective available to observers embedded within spacetime. Within this structure, definite outcomes arise when components of a system’s state become associated with distinguishable physical records in spacetime, a condition termed Structural Observability. Quantum probabilities then arise from the structural limitations imposed by the L-ORF description rather than from fundamental randomness in the underlying configuration. The framework preserves the standard mathematical formalism of quantum mechanics—Hilbert space, unitary evolution, and the Born rule—while providing a structural account of why these elements appear in the observational description.
