ALP Seminar: Quantum telescopes and quantum imaging

Quantum mechanics has revolutionised information processes like computing and communication. However, full-scale quantum networks and quantum computing are still years away. In the short term we can expect benefits from quantum technologies in the areas of sensing and metrology. In this talk I will present the foundations of quantum imaging and metrology, and explore how we can use quantum entanglement to improve telescopes. I will give a brief overview of some relevant experiments that have shown an improvement in resolution and/or noise by adopting quantum technologies, and explore some of the open questions in the field, particularly how multi-photon processes can gain improvements in resolution.
