Enhancing the resolution in imaging is crucial for many fields in science and technology but is always hampered by the diffractionlimit. Treating light fields as quantum systems, quantum information theory show that it is possible to fundamentally break thediffraction limit by demultiplexing the optical field into different spatial modes. However, the way to approach the quantum limit forfull imaging remains unclear and it is challenging to realize quantum-limited super-resolution for truly microscopic objects. To tacklethis problem, the proposed research aims to: (1) identify the quantum resolution limit for full imaging; (2) develop a practical anduniversal imaging method towards the quantum limit; (3) realize the prototype of quantum-limited far-field microscope. Throughcomprehensive training on both research and transferable skills, this action will diversify the applicant's competences for academicleadership.The research will integrate multidisciplinary and interdisciplinary approaches, combining (1) quantum tomography and statisticalanalysis with Fisher information formalism, (2) spatial mode manipulation and detection of light, and (3) nano-optics/microscopy toestablish quantum estimation theory of full imaging, develop novel detection techniques, perform microscopic imaging and evaluateits advantages over conventional imaging.The 3 research objectives correspond to 3 progressive research work packages to ensure the success of the fellowship, together witha variety of dissemination/exploitation plans to maximize the impact of the action. The proposed objectives, if successful, will result ina revolutionary imaging technology with a potential to change the faces of all fields of science and technology that involve opticalimaging, ranging over astronomy, biology, medicine and nanotechnology, as well as optomechanical industry.

增强成像分辨率对于科学和技术的许多领域至关重要，但总是受到衍射限制的阻碍。将光场视为量子系统，量子信息理论表明，可以通过将光场倒入不同的空间模式来从根本上打破thediffraction限制。但是，接近量子限制成像成像的方法尚不清楚，实现真正的显微镜对象的量子限制的超分辨率是一项挑战。为了解决问题，拟议的研究目的是：（1）确定完整成像的量子分辨率限制； （2）开发一种实用的和附加成像方法，以实现量子极限； （3）实现量子限制的远场显微镜的原型。通过对研究和可转移技能的综合培训，该行动将使申请人在学术界方面的能力多样化。该研究将整合多学科和跨学科的方法，将（1）量子层析成像和统计分析与渔民信息形式主义与空间模式的操纵和量级估计，以及（3）Nano-imcoppiration in nanano-imcoppiration in nanano-imcopips contiment（2）新型检测技术，进行微观成像并评估比常规成像的优势。3个研究目标对应于3个渐进研究工作包，以确保团契的成功，以及各种传播/开发计划，以最大程度地提高行动的影响。拟议的目标，如果成功的话，将导致INA革命性成像技术，并有可能改变涉及光学图像，范围涉及天文学，生物学，医学和纳米技术以及光学机械行业的各个科学和技术领域的面孔。
