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，这种干涉仪在几米内离域，并持续数秒。它们前所未有的灵敏度允许与相干或纠缠物质一起测试叠加原理，与A02一起测试，以及与B09一起测试后牛顿引力的传感效应。A05将与A05密切合作，开发在设计原子量子态以及相干动量转移和干涉仪拓扑方面超越最先进水平的必要方法。这些进展有助于DQ-MAT实现增强量子传感器和用于测试基础物理的计量学的目标。

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.
