We propose a method to prepare and verify spatial quantum superpositions of a nanometer-sized object separated by distances of the order of its size. This method provides unprecedented bounds for objective collapse models of the wave function by merging techniques and insights from cavity quantum optomechanics and matter-wave interferometry. An analysis and simulation of the experiment is performed taking into account standard sources of decoherence. We provide an operational parameter regime using present-day and planned technology.
我们提出了一种制备和验证纳米级物体之间的空间量子叠加的方法，这些物体之间的距离达到了其尺寸量级。这种方法通过合并腔量子光力学和物质波干涉测量技术和见解，为波函数的客观塌缩模型提供了前所未有的限制。考虑到标准的退相干源，我们对实验进行了分析和模拟。我们使用当前和计划的技术提供了一个操作参数范围。
