The teams — one led by Jian-Wei Pan at the University of Science and Technology of China, the other by his former PhD supervisor Anton Zeilinger of the University of Vienna — have spent the last 7 years beating each other's distance records for long-distance quantum-teleportation. They now plan plan to create the first intercontinental quantum-secured network, connecting Asia to Europe by satellite."

simple instructions such as 'go left', 'go right', and 'build car'."
