Juan Yin is professor for experimental physics at the University of Science and Technology of China (USTC). She was also appointed as the chief designer of the entangled-photon source payload on Micius quantum science satellite. Her research directions include the foundational tests of quantum physics and large-scale quantum network. Some recent representative scientific contributions include the achievement of satellite-based entanglement distribution and secure quantum cryptography over thousand kilometers. She has so far published more than 40 papers in international journals, including 5 in Nature, 2 in Science, 2 in Nature Photonics, one each in Nature Physics and PNAS, and 9 in Physical Review Letters. Till now, her publications have been cited more than 2700 times. Her work has been selected for twice annual highlights by Nature as “Features of the Year 2012”, ”2017 in news: The science events that shaped the year”, and three times “The Top Ten Annual Scientific and Technological Progresses in China” by the academicians of the Chinese Academy of Science.

Quantum Experiments at Space Scale

Free-space quantum experiments with satellites opens a promising avenue for global secure quantum network and large-scale test of quantum foundations. Quantum Science Satellite has been launched on August 16th 2016. We have implemented a series of satellite-ground experimental works, including satellite-based entanglement distribution, quantum teleportation and quantum key distribution (QKD), and also intercontinental quantum communication between China and Europe. Here we will also introduce some recent progresses, such as entanglement-based QKD without the need for trusted relays, integrated space-to-ground quantum communication network over 4,600 km. I will finally focus on the technical challenges, possible solutions and related research work we are carrying out towards global quantum network.
