摘要：

拟议的MAQRO任务的目标是利用空间实现长自由落体时间、极端真空、纳米重力和低温，以测试宏观量子实验中的物理学基础。这将导致新型量子传感器的发展，以及在与重力的界面上探测量子物理基础的手段。早期的研究表明，该提议是可行的，但仍存在一些关键挑战，需要开发关键技术。这些新技术将为实现更多的科学目标开辟潜力。拟议的研究活动旨在推进最先进的技术，并在太空中进行第一次宏观量子实验。地面、微重力和空间实验将在本十年期间推动拟议的研究活动，以便能够在下一个十年内实施MAQRO。

英文摘要：

The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations of physics in macroscopic quantum experiments. This will result in the development of novel quantum sensors and a means to probe the foundations of quantum physics at the interface with gravity. Earlier studies showed that the proposal is feasible but that several critical challenges remain, and key technologies need to be developed. These new technologies will open up the potential for achieving additional science objectives. The proposed research campaign aims to advance the state of the art and to perform the first macroscopic quantum experiments in space. Experiments on the ground, in micro-gravity, and in space will drive the proposed research campaign during the current decade to enable the implementation of MAQRO within the subsequent decade.
