Quantum meronomic frames

TL;DR

This paper explores how composite quantum systems can be decomposed into subsystems, defining meronomic frames, and demonstrates how asymmetric states can encode these frames for quantum information tasks.

Contribution

It introduces the concept of meronomic frames in quantum systems and shows how asymmetric states can serve as references for subsystem decompositions.

Findings

Meronomic frames are a new way to characterize subsystem decompositions.

Asymmetric quantum states can encode information about meronomic frames.

The framework enables new quantum information processing tasks.

Abstract

Composite quantum systems can be decomposed into subsystems in many different inequivalent ways. We call a particular decomposition a meronomic reference frame for the system. We apply the ideas of quantum reference frames to characterize meronomic frames, identify tasks that require such frames to accomplish, and show how asymmetric quantum states can be used to embody meronomic frame information.
