Measurement as a Coordination Breakdown A Foundational Clarification on the Quantum–Classical Transition

This note reframes the quantum measurement problem as a physical boundary condition rather than a dynamical or interpretive paradox. It argues that measurement corresponds to the point at which global coordination of quantum phase information becomes physically impossible due to fundamental limits imposed by relativistic causality, thermodynamic irreversibility, and information transfer constraints. Classical outcomes emerge not from wavefunction collapse or observer intervention, but because coherent quantum description cannot be sustained once synchronization demands exceed the universe’s finite coordination capacity. The work introduces measurement as a coordination breakdown, grounding the quantum–classical transition in physical realizability rather than additional postulates or modifications to quantum mechanics.
