In terms of policies, China has issued a number of policies to promote the development of quantum communication. The Tenth Five-Year Plan implemented in 20021proposes that the R&D investment of the whole society will increase by more than 7% annually, and quantum technology will be listed as the key R&D object together with artificial intelligence and semiconductors.
In terms of technology, China has more than 3,000 quantum communication patents, ahead of the United States. With the country gradually improving the top-level design in the field of quantum science and technology and strengthening technical support, China is expected to become the main promoter of the global research and application of quantum information technology.
Quantum communication has obvious advantages over traditional communication.
Compared with traditional communication technology, the characteristics and advantages of quantum communication technology are high timeliness, strong anti-interference, good confidentiality and low required signal-to-noise ratio. The delay of quantum communication line is almost zero, the information transmission speed is fast and the process is barrier-free; The information transmission in quantum communication has nothing to do with the communication media of both parties, is not affected by the space environment, and has good anti-interference performance;
Because quantum can't be cloned, it becomes the basis of quantum keys. Quantum cryptography is highly secure and generally cannot be cracked. Compared with traditional communication means, under the same conditions, the signal-to-noise ratio required by quantum communication technology to obtain reliable communication is 30-40dB lower.
The 14th Five-Year Plan has promoted the development of quantum communication.
China has issued many policies to promote the development of quantum communication. The 14th Five-Year Plan implemented in 20021proposes that the R&D investment of the whole society will increase by more than 7% annually, and quantum technology, artificial intelligence and semiconductors will be listed as key R&D targets.
During the Tenth Five-Year Plan period, it is necessary to strengthen the innovative application of key digital technologies, speed up the layout of frontier technologies such as quantum computing and quantum communication, organize and implement future industrial incubation and acceleration plans in frontier science and technology and industrial transformation fields such as quantum information, and plan future industrial layout. China will build a complete wide-area quantum communication network technology system integrating heaven and earth, and take the lead in promoting the wide application of quantum communication technology in finance, government affairs, energy and other fields.
In the 2002 1 March1May-March 21communication sector, only quantum communication rose by 3. 1%, while others such as mobile internet, satellite communication navigation, blockchain, cloud computing and Internet of Things all fell. It can be seen that the performance of the communication sector has declined, but the performance of quantum communication is the best, which shows that the development momentum of quantum communication is good.
China has more than 3,000 quantum communication patents, leading the United States.
After the "Snowden Incident" on 20 13, China vigorously developed quantum communication and key technologies. In 20 16, China successfully launched the world's first quantum science experimental satellite "Mozi", and obtained many international leading scientific achievements such as quantum key distribution, quantum teleportation and entanglement distribution within thousands of kilometers.
In 2020, the US government proposed a plan to build a quantum Internet; China is also building a quantum communication system, and China University of Science and Technology announced the successful establishment of a quantum communication network spanning 4,600 kilometers.
According to Japanese information analysis agency VALUENEX, China has obvious advantages in hardware-related patents such as optical quantum switches: Huawei has 100 patents, ranking second in the world; Beijing University of Posts and Telecommunications holds 84 patents, ranking fourth.
In terms of software, China also has strong strength. China has built a quantum communication network connecting Beijing and Shanghai, and accumulated knowledge and experience in equipment development and application. China has more than 3,000 quantum communication patents, far ahead of the United States.
Quantum communication is developing to the quantum Internet.
Quantum communication technology is an important means to ensure information security in the future and an industry supported by the state. The emergence of new technologies, applications and models such as cloud computing, mobile Internet, Internet of Things and big data has put forward new requirements for information security, involving national security and social stability. China has upgraded information security to a national security strategy.
In recent years, China has accelerated its development in the field of quantum science and technology, and has a good practical foundation and development conditions in related research funds, patent application layout and application exploration. With the country gradually improving the top-level design in the field of quantum science and technology, China's quantum science and technology industry will develop rapidly and become the main promoter of global quantum information technology research and application.
