连续自发局域化（英语：Continuous spontaneous localisation，CSL）是一个模型，它捕捉了量子理论的一类扩展的影响，这些扩展预计将由量子引力产生，并且使得波函数坍缩是一个物理过程。这样一个过程的速率可能比迄今为止通过搜索设定的上限低得多，但仍然大大修改了量子力学的解释，并解决了量子测量问题。因此，实验试图探索这一点。我们描述了一个实验，有可能延长CSL的灵敏度的许多数量级。该方法是检测加热的带电宏观物体的运动限制在保罗陷阱。讨论了检测方法和主要噪声源。我们发现，CSL与标准参数可以观察到使用振动隔离离子阱的大小为1\，{\rm cm}在超低压下，与光学干涉检测。
Continuous spontaneous localisation (CSL) is a model that captures the effects of a class of extensions to quantum theory which are expected to result from quantum gravity, and is such that wavefunction collapse is a physical process. The rate of such a process could be very much lower than the upper bounds set by searches to date, and yet still modify greatly the interpretation of quantum mechanics and solve the quantum measurement problem. Consequently experiments are sought to explore this. We describe an experiment that has the potential to extend sensitivity to CSL by many orders of magnitude. The method is to detect heating of the motion of charged macroscopic objects confined in a Paul trap. We discuss the detection and the chief noise sources. We find that CSL with standard parameters could be observed using a vibration-isolated ion trap of size 1\,{\rm cm} at ultra-low pressure, with optical interferometric detection.
