The world's first quantum micro -nano satellite launch successfully!China won again this time!

On July 27, the world's first quantum micro -nainer was successfully launched. This satellite was jointly developed by many units such as the University of Science and Technology of China, Hefei National Laboratory, and Jinan Quantum Technology Research Institute. This news immediately aroused global attention. After all, quantum technology is the top technology that countries around the world are working hard to break through, and many countries have repeatedly encountered bottlenecks during the research and development process, and China's quantum technology development currently ranks first in the world.

What is the use of this satellite?

Obviously, our country is not the first time to launch a quantum satellite. Now that it can be called "first", it must mean that this quantum satellite must be used for new technologies.

This satellite mainly highlights the characteristics of "micro". Compared with all the satellites launched globally before, this satellite has tended to be miniaturized from WeChat body to the ground station. Officially announced that this satellite is based on the construction of micro -nano satellites and miniaturized ground stations. Compared with the previous quantum satellites, the satellite cost is lower and the work efficiency is higher.

And only one purpose of launching this quantum micro -satellite -establish a real -time star quantum key distribution, high efficiency, and practicality of world integrated quantum confidential communication system, improve the coverage of quantum communication networks, reduce its construction costs, and to asks for its construction costs. The nationalization and commercialization of quantum communication laid the foundation.

Quantum communication is about to be nationalized

Because it is unable to be eavesdropped and cannot be cracked by the computer, quantum communication is also regarded as "absolute security". In this case, quantum communication is regarded as the best direction in the future development of communication.

1. Because quantum has the characteristics of observation and exploration -as long as it is observed during the transmission process, the quantum will collapse immediately, and its trait will change huge Essence

2. Due to the encryption transmission of information during the quantum communication process, the keys are full of randomness in this process. In this case, even if the information is intercepted, it is difficult for technical staff to crack through the key to obtain communication information to obtain communication information Therefore, quantum communication has strong security.

3. In addition, quantum communication also has strong anti -interference.

However, there are many difficulties in the development of quantum communication. The biggest dilemma is the issue of cost and coverage. Although our country launched the Mozi satellite in 2016 and led the global quantum technology field early. But it is not easy to commercial use of quantum communication technology.

On the one hand, the cost is too high. The "Mozi" satellite light costs 669 million US dollars. Such a high cost is doomed to quantum communication if there is no way to reduce costs, it is impossible to achieve popularity. After all, a satellite cannot cover the country.

On the other hand, it is coverage. To achieve quantum communication nationwide, we need to launch at least a hundred quantum satellites. We will find that the cost of combining the "Mozi" is simply unbearable at all. And it takes a long time to launch so many quantum satellites.

Therefore, miniaturization and miniature are important ways to develop quantum communication. Now the first quantum micro -nano satellite successful launch means that we have achieved technological breakthroughs. I believe that in the future, we will definitely achieve technical breakthroughs. (Huo Hao)
