Innovation and Openness,Key to China’s Sci-tech Progress

摘要

MOST people make several phone calls a day and very few keep records of the date and time.But the call made between Austrian physicist Anton Zeilinger,who won the Nobel Prize in phys­ics this year,and Bai Chunli,then president of the Chinese Academy of Sciences(CAS),on September 29,2017,has gone down in the annals of quantum science as the first intercon­tinental quantum-secure communication video call.Bai was in Beijing and Zeilinger in Vienna,and the communication was possible through a sophisticated Chinese research satel­lite named Micius,the world’s first quantum communication satellite developed and launched into orbit by the CAS just the year before.
