Macroscopically delocalised quantum states of matter (B07)

B07项目将创建和研究具有宏观波函数的干涉仪，这些波函数在几米内离域并持续数秒。它们前所未有的灵敏度允许与A02一起测试相干或纠缠物质的叠加原理，并与B09一起感知后牛顿引力效应。在原子量子态设计、相干动量传递和干涉仪拓扑等方面，将与A05密切合作，发展超越当前最先进水平的必要方法。这些进步有助于DQ-mat增强量子传感器和计量学的目标，以测试基础物理。

Project B07 will create and investigate interferometers with macroscopic wave functions, that are delocalised over metres and persist over seconds. Their unprecedented sensitivities allow for testing the superposition principle with coherent or entangled matter together with A02 and sensing effects of post-Newtonian gravity together with B09. The necessary methods for exceeding state-of-the-art in designing atomic quantum states as well as the coherent momentum transfer and interferometer topologies will be developed in close cooperation with A05. These advances contribute to DQ-mat’s goal of enhancing quantum sensors and metrology for testing fundamental physics.
