Micro-Macro Duality and Emergence of Macroscopic Levels

TL;DR

This paper proposes a unified framework linking quantum micro and classical macro levels through measurement and amplification processes, offering insights into the emergence of spacetime structure.

Contribution

It introduces a unified formulation of instruments that describe measurement and amplification, providing a new perspective on the emergence of macroscopic phenomena from quantum micro levels.

Findings

Unified description of measurement and amplification processes.

Insights into the emergence of spacetime structure.

Clarification of quantum-classical relation.

Abstract

The mutual relation between quantum Micro and classical Macro is clarified by a unified formulation of instruments describing measurement processes and the associated amplification processes, from which some perspective towards a description of emergence processes of spacetime structure is suggested.
