Abstract

We propose an experimentally accessible, objective measure for the macroscopicity of superposition states in mechanical quantum systems. Based on the observable consequences of a minimal, macrorealist extension of quantum mechanics, it allows one to quantify the degree of macroscopicity achieved in different experiments.

摘要

我们提出了一种可实验验证的、用于机械量子系统中叠加态宏观性的客观度量方法。该方法基于对量子力学的最小扩展的可观测结果，可用于量化不同实验中实现的宏观性程度。
