The latest outline of the Yangtze River Delta regional integration development plan (hereinafter referred to as the Outline) proposes to build a new generation of information infrastructure in coordination, promote the information infrastructure to reach the worlds advanced level, build a high-speed ubiquitous information network, and jointly build a digital long triangle.

In particular, the outline mentioned that the Yangtze River Delta data center should be planned as a whole, the construction of regional information hub port should be promoted, and the coordinated layout of data center and storage and calculation resources should be realized. Accelerate the development of quantum communication industry, make overall layout and planning for the construction of quantum secure communication trunk network, realize seamless connection with national wide area quantum secure communication backbone network, and carry out quantum communication application pilot.

The first commercial area of quantum communication in China

Prior to that, the national development and Reform Commission issued a notice to build quantum confidential communication backbone network and man in key areas such as Beijing Tianjin Hebei and Yangtze River economic belt, based on the quantum scientific experimental satellites of quantum secure communication Jinghu trunk line and Mozi, in response to the national strategic demand and sustainable operation requirements. In 2018, with the approval of the national development and Reform Commission, Guoke quantum communication network Co., Ltd. under the Chinese Academy of Sciences undertook the task of building the first phase of the national wide area quantum confidential communication backbone network.

According to the prospectus of kedaduodun quantum (hereinafter referred to as GuoDun quantum), which is going to land on the science and technology innovation board, Guangzhou, Xian, Chengdu, Guiyang, Chongqing, Nanjing, Haikou, Urumqi, Suzhou and other places have launched local quantum secure communication man planning. According to the data at the end of 2018, more than 7000 kilometers of practical optical fiber quantum secure communication network has been realized in China.

People familiar with the matter disclosed to the first financial reporter that other backbone networks, including Beijing Guangzhou and Beijing Harbin lines, are also in the process of project approval. In addition, Shanghai Nanjing Hefei Wuhan Chongqing Chengdu and Hefei Zhengzhou Xian Lanzhou Urumqi backbone networks are also under planning.

In terms of trunk network, the Yangtze River Delta urban agglomeration quantum communication commercial project is also under construction and planning.

Jiangsu optical fiber communication enterprise Hengtong group and Anhui questionsky Quantum Technology Co., Ltd. of China University of science and technology have cooperated to open the first demonstration project of quantum secure communication line in Jiangsu. At present, Nanjing Suzhou trunk line has been built from Nanjing to Suzhou, mainly serving government affairs.

According to the plan, on this basis, around the integrated development of the Yangtze River Delta, from Nanjing to Hefei, Hefei to Hangzhou, Hangzhou to Shanghai, we will build a private line to form a quantum security trunk ring network of the Yangtze River Delta urban agglomeration. After the completion of the whole network construction, it will cover 16 major cities in the Yangtze River Delta, with a total length of 1013 km. It is expected that after the completion of the project, the Yangtze River Delta urban agglomeration will become the first quantum communication commercialization area in China, greatly improving the level of regional information security, and finally becoming the global quantum communication leading demonstration area.

In the core area of the Yangtze River Delta, Shanghai Zhangjiang has also built Shanghai Lujiazui financial quantum secure communication Demonstration Network and Shanghai quantum secure communication master control and big data service center project. Finally, 1025 kilometers of optical fiber lines have been completed, forming Lujiazui financial network with six relay stations.

Acceleration of industry standardization

A person in the quantum communication industry pointed out to the first financial reporter that to access the backbone network, the trunk network must first meet the standard of access if you dont want to. At present, the standards of quantum communication industry at home and abroad are being formulated, such as the International Telecommunication Union (ITU), the Standardization Technical Committee of the cryptography industry at home, China Communication Standardization Association, etc., which are actively promoting the process of quantum communication standardization.

The introduction of relevant policies will undoubtedly benefit the whole industry, accelerate the formulation of industry standards and the development of downstream application market, the core personnel of a domestic enterprise involved in the formulation of domestic quantum communication standards told the first financial reporter At present, quantum communication has been used in finance, power, national defense, government and other related fields.

At present, among the quantum communication enterprises in China, GuoDun quantum has been successfully listed on the science and technology innovation board and is expected to be listed in the near future. According to GuoDun quantums prospectus, at this stage, the customers are mainly the builders of quantum confidential communication backbone network, man and system integrators serving the builders.

The prospectus also said that compared with traditional cryptography, quantum key products are temporarily at a disadvantage in terms of stability and cost. But in the long run, with the chip development and scale application of quantum key distribution products, the gap between cost and price will gradually narrow.

Hefei high tech Zone, located in the triangle of the regional director, also breeds a number of quantum technology enterprises like GuoDun quantum. At present, the national quantum secure communication Beijing Shanghai trunk line and quantum science experimental satellite Hefei General Control Center are set up in the high tech Zone, which is the first to carry out large-scale quantum remote secure communication application projects in the world.

In recent years, the quantum communication industry has been receiving increasing policy codes. In December 2016, the State Council issued the 13th five year plan for the development of national strategic emerging industries, which promotes quantum communication to a national strategic level and takes it as an important strategic emerging industry direction and a major science and technology project reflecting the national strategic intention.

In November 2017, the national development and Reform Commission issued the notice on organizing the implementation of the new generation information infrastructure construction project in 2018, proposing to build the quantum confidential communication backbone network in Beijing, Tianjin, Hebei, Yangtze River economic belt and other key regions based on the quantum secure communication Jinghu trunk line and Mozi quantum scientific experimental satellite, in response to the national strategic needs and sustainable operation requirements Metropolitan area network, and in a number of areas to build satellite ground stations, the formation of quantum secure communication backbone ring network. At the same time, the operation service system of quantum secure communication network is constructed to further promote its application in the field of information communication, government affairs, finance, power and other industries.

In March 2018, the government work report affirmed the development achievements of quantum communication, listed quantum communication, manned space flight, deep sea exploration and large aircraft as major innovation achievements, and recognized the status and development achievements of quantum communication industry.

According to the statistical data of the analysis report on the market prospect and investment strategy of Chinas quantum communication industry issued by the prospective industry research institute, the market scale of Chinas quantum communication industry will reach 42.5 billion yuan in 2019, and the market scale of Chinas quantum communication industry will exceed 80 billion yuan in 2023, reaching about 80.5 billion yuan, with an average compound growth rate of 17.31% in 2019-2023.
