我们建立了一个客观的方案，以确定与力学自由度的量子叠加试验的宏观性。它是基于贝叶斯假设证伪的一类宏观实在论修改的量子理论，如模型的连续自发局域化。该测量使用实验中收集的原始数据，考虑到所有测量不确定性，并可用于直接评估任何可能的量子力学测试。我们确定所产生的宏观量子物理学的三个最近的测试：双井干涉的玻色-爱因斯坦凝聚，Leggett-Garg测试与原子随机游走，纠缠产生和读出的纳米机械振荡器。
We establish an objective scheme to determine the macroscopicity of quantum superposition tests with mechanical degrees of freedom. It is based on the Bayesian hypothesis falsification of a class of macrorealist modifications of quantum theory, such as the model of continuous spontaneous localization. The measure uses the raw data gathered in an experiment, taking into account all measurement uncertainties, and can be used to directly assess any conceivable quantum mechanical test. We determine the resulting macroscopicity for three recent tests of quantum physics: double-well interference of Bose-Einstein condensates, Leggett-Garg tests with atomic random walks, and entanglement generation and read-out of nanomechanical oscillators.
