Recently, the U.S. Department of energy released a report entitled “strategic blueprint for building a national quantum Internet within 10 years, and hopes to ensure that the United States is in the forefront of the global quantum competition and lead the new era of communication. According to the US Department of energy, the quantum Internet can transmit information more safely than existing networks by using the laws of quantum mechanics, which is almost unbreakable, and will have a profound impact on key fields such as science, industry and national security in the future. < p > < p > quantum Internet can not only be used to transmit encrypted information, but also support cloud based quantum computing, which is expected to show its talents in many fields. According to the report of the US Department of energy, the quantum Internet it is preparing to build will first be used in the banking and medical service sectors, and it is expected to play an important role in the fields of national security and aircraft communication in the future. In addition, the creation of super sensitive quantum sensor networks will help to better detect and predict earthquakes, or to find underground oil, gas or minerals. < p > < p > according to the report, the quantum Internet is evolving step by step, integrating various functions such as quantum computing, quantum sensing and measurement, and the ultimate goal is to form a “full quantum network” including quantum security network, distributed quantum computing and quantum sensor network. In view of the high security and wide application fields of quantum Internet, many countries are developing this new communication mode. The Netherlands, Canada, Japan, South Korea, Russia and EU countries are stepping up the deployment of quantum network construction. < p > < p > in recent years, China is also vigorously developing quantum communication technology, and has made remarkable achievements in the field of quantum communication: in 2017, the world’s first quantum secure communication backbone line “Beijing Shanghai trunk line” with a total length of more than 2000 kilometers passed the general technical acceptance; in June this year, pan Jianwei research team of the University of science and technology of China used the world’s first quantum science experimental satellite Mozi, for the first time in the world, has realized quantum secure communication based on entanglement without relay at the level of 1000 kilometers.
