Building Entanglement Distribution Networks
Optica Distinguished Lecture Series on Quantum Science and Technology
Entanglement correlations allow distributed quantum systems to be described in the same physical state, and is a resource for many of the technologies that we call Quantum 2.0. What is a practical distance over which we can distribute entanglement? In this session, I will review and discuss the physical layer of the entanglement distribution network, including both ground and space segments. I will share some of the lessons we have learned in deploying quantum systems outside the lab and hope to share some of the latest findings from our experiments.
About the Speaker
Professor Alexander Ling, a Principal Investigator from the Centre for Quantum Technologies (CQT) at the National University of Singapore (NUS), has been named Distinguished International Associate (DIA) by the United Kingdom’s (UK) Royal Academy of Engineering for his strong track record of work in quantum communication and quantum networking. He is among 10 researchers and the sole awardee in Singapore selected for the 2024 DIA program, which provides a grant to support his collaborations with UK scientists on quantum space technologies for one year.
His team has been involved in four launch campaigns that place quantum experiments in space. One of these campaigns led to the 2019 deployment of the SpooQy-1 satellite demonstrating entangled photon generation on a nanosatellite. In 2024, his team also participated in the Space Entanglement and Annealing QUantum Experiment (SEAQUE) mission that will test self-healing quantum detectors on the International Space Station.
