Contextual Measurement Model and Quantum Theory

TL;DR

The paper introduces the contextual measurement model (CMM) that clarifies quantum foundations, aligns with Bohr's views, and applies to classical, quantum, semi-classical physics, as well as cognition and decision-making.

Contribution

It develops the CMM based on contextual probability theory, connecting generalized probability with quantum and classical measurement frameworks.

Findings

CMM unifies classical, quantum, and semi-classical measurements.

Illustrates CMM with examples including von Neumann and quantum instrument theories.

Demonstrates applicability of CMM in cognition and decision-making models.

Abstract

We develop the contextual measurement model (CMM) which is used for clarification of the quantum foundations. This model matches with Bohr's views on the role of experimental contexts. CMM is based on contextual probability theory which is connected with generalized probability theory. CMM covers measurements in classical, quantum, and semi-classical physics. The CMM formalism is illustrated by a few examples. We consider CMM framing of classical probability, the von Neumann measurement theory, the quantum instrument theory. CMM can also be applied outside of physics, in cognition, decision making, and psychology, so called quantum-like modeling.
