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镜头的基础物理原理，以便设计出能够对亚波长结构进行成像的新型镜头。这种透镜对于量子技术很重要，因为它们允许单个原子量子位以近乎完美的方式通过光耦合。它们还将在量子传感和生命科学领域得到应用。我们希望研究的镜头之一是麦克斯韦鱼眼镜头 (MFEL)。根据几何光学，这是一个完美的镜头。然而，MFEL 的波动理论存在争议，并且似乎需要耗散（非厄米）元素。通过与无标度势中量子粒子行为的密切类比，我们将采用量子尺度异常的方法来解决这个问题。我们的合作将汇集伯明翰大学在奇异光学方面拥有专业知识的团队与麦克马斯特大学在量子异常方面拥有经验的团队。伯明翰拥有英国传感器和计时量子技术中心以及拓扑博士培训中心。所有这些结合起来将为学生提供提案领域的大量专业知识和极好的培训机会。
