The goal of the proposed collaboration is to understand the fundamental physics underlying super-resolving lenses so that new types can be designed that are capable of imaging subwavelength structures. Such lenses are important for quantum technology because they allow individual atomic qubits to be coupled by light in a near perfect fashion. They will also have applications in quantum sensing and the life sciences. One lens we wish to investigate is Maxwell's Fish Eye Lens (MFEL). According to geometric optics this is a perfect lens. However, the wave theory of the MFEL is controversial and seems to require a dissipative (non-hermitian) element. Using a close analogy to the behaviour of quantum particles in scale free potentials, we will bring the methods of quantum scale anomalies to bear on this problem. Our collaboration will bring together a team from the University of Birmingham that has expertise in singular optics with a team from McMaster that has experience in quantum anomalies. Birmingham hosts the UK's Quantum Technology Hub for Sensors and Timing and also a Centre for Doctoral Training on topology. All combined this will provide a large amount of expertise in the area of the proposal and excellent training opportunities for students.

拟议的合作的目的是了解超出分辨率镜头的基本物理学，以便可以设计出能够成像亚波长度结构的新型类型。这样的镜头对于量子技术很重要，因为它们允许单个原子量子量接近完美的方式。他们还将在量子传感和生命科学中应用。我们希望调查的一个镜头是麦克斯韦的鱼眼镜（MFEL）。根据几何光学元件，这是一个完美的镜头。但是，MFEL的波理论是有争议的，似乎需要耗散性（非热）元素。使用比喻与量子粒子在自由势方面的行为的类比，我们将带来量子标度异常的方法，以解决此问题。我们的合作将汇集伯明翰大学的一支团队，该团队与麦克马斯特（McMaster）具有量子异常经验的团队具有奇异光学的专业知识。伯明翰主持了英国的传感器和计时量子技术枢纽，也是拓扑培训的中心。所有这些都将在提案领域提供大量专业知识，并为学生提供出色的培训机会。
