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.

拟议合作的目标是了解超分辨透镜的基本物理原理，以便设计出能够成像亚波长结构的新类型。这种透镜对量子技术很重要，因为它们允许单个原子量子比特以近乎完美的方式与光耦合。它们还将在量子传感和生命科学中应用。我们希望研究的一种透镜是麦克斯韦鱼眼透镜（MFEL）。根据几何光学，这是一个完美的透镜。然而，MFEL的波动理论是有争议的，似乎需要一个耗散（非厄米）元素。使用一个密切的类比量子粒子在无标度势的行为，我们将使量子标度异常的方法来承担这个问题。我们的合作将汇集来自伯明翰大学的一个团队，该团队具有奇异光学的专业知识，来自麦克马斯特的一个团队具有量子异常的经验。伯明翰拥有英国的传感器和定时量子技术中心，以及拓扑学博士培训中心。所有这些结合起来，将为学生提供大量的建议领域的专业知识和良好的培训机会。
