The central goal of the project is to understand the ultimate resolution of imaging systems based on methods from quantum metrology. Previous analyses were based on classical wave mechanics and led to well-known bounds such as Rayleigh's or Abbey's diffraction limit, according to which the resolution of e.g. microscopes cannot be significantly better than the wavelength of the used light. These limits are, however, in conflict with clearly better, experimentally confirmed resolutions that can be achieved through appropriate measurement procedures and have meanwhile come to play an important role in biology. In contrast to those classical analyses, the project aims at calculating the resolution of optical imaging systems such as microscopes or telescopes only based on the laws of quantum mechanics. To that end, imaging will be formulated as a problem of quantum metrology, where a multitude of image parameters are coded in the quantum mechanical system "light", and the task is then to measure these parameters as precisely as possible. Measurement procedures shall be developed theoretically that come as close as possible to the so established bounds of resolution.

该项目的中心目标是了解基于量子计量方法的成像系统的最终分辨率。以前的分析是基于经典的波动力学，并导致众所周知的边界，如瑞利或修道院的衍射极限，根据该极限，例如显微镜的分辨率不能明显优于所使用的光的波长。然而，这些限制与通过适当的测量程序可以实现的明显更好的实验证实的分辨率相冲突，同时在生物学中发挥重要作用。与这些经典分析相反，该项目旨在仅基于量子力学定律计算光学成像系统（如显微镜或望远镜）的分辨率。为此，成像将被公式化为量子计量学的问题，其中大量的图像参数被编码在量子力学系统“光”中，然后任务是尽可能精确地测量这些参数。 应在理论上制定测量程序，使其尽可能接近所确定的分辨率范围。
