Unified Cosmic Mechanics Evolution Theory (XVII) Quantum Entanglement — Single-Particle Coordinated Evolution and Three-Layer Angular Momentum Conservation

Traditional quantum mechanics interprets quantum entanglement as non-local statistical correlation, but fails to answer the underlying physical mechanism of entanglement: what "maintains" the correlation between entangled particles? Why can this correlation transcend spatial distance? Based on the framework of the Unified Cosmic Mechanics Evolution Theory, this paper proposes that the essence of quantum entanglement is an inline perception protocol that maintains the coordinated evolution of multiple momentum units. The core conclusions include: (1) The core role of quantum entanglement is to support the conservation of carrier angular momentum, which is the fundamental premise for particles to realize spin and macroscopic rotation — a single momentum unit cannot rotate, and "rotatability" is an emergent property of the entanglement protocol. (2) A single elementary particle has three coordinated evolution forms (collapsed, diffused, fluid), and the state transition depends on the internal structure and coordinated evolution ability endowed by the quantum entanglement protocol. (3) The multi-particle entangled state can be regarded as "single-particle coordinated evolution" at the macroscopic level, which originates from the multi-layer encapsulation characteristics of momentum units m₀·c. (4) The core mechanism for quantum entanglement to realize superluminal action is perceptual angle interlocking — establishing a logical correlation independent of geometric distance through an inline protocol, rather than trans-spatial propagation. (5) Both instantaneous force interaction and quantum tunneling can be reconstructed as local potential space momentum borrowing and returning state transition processes, without relying on propagator flight. This paper further argues that quantum entanglement, elementary force interaction, and quantum tunneling are not isolated phenomena, but three manifestations of the same set of momentum topological coding and potential space borrowing and returning mechanisms under different boundary conditions — entanglement is a static protocol maintaining structural stability, force is a dynamic state update after protocol triggering, and tunneling is a potential space topological transition guided by the protocol. This framework reduces quantum mechanics to a deterministic information dynamics evolution process based on protocol rules, providing a new ontological support for understanding the causality of the microcosm.
