Quantum hypothesis testing has shown the advantages that quantum resources can offer in the discrimination of competing hypothesis. Here, we apply this framework to optomechanical systems and fundamental physics questions. In particular, we focus on an optomechanical system composed of two cavities employed to perform quantum channel discrimination. We show that input squeezed optical noise, and feasible measurement schemes on the output cavity modes, allow to obtain an advantage with respect to any comparable classical schemes. We apply these results to the discrimination of models of spontaneous collapse of the wavefunction, highlighting the possibilities offered by this scheme for fundamental physics searches.

量子假设检验显示了量子资源在区分竞争假设方面可以提供的优势。在这里，我们将此框架应用于光机械系统和基本物理问题。特别是，我们专注于由两个腔组成的光机械系统，用于执行量子通道鉴别。我们展示了输入压缩光学噪声和输出腔模式的可行测量方案，允许获得相对于任何可比经典方案的优势。我们将这些结果应用于波函数自发坍缩模型的鉴别，突出了该方案为基础物理学搜索提供的可能性。
