Entering the Future Science City located in the northern suburbs of Hefei, the construction site of the Compact Fusion Energy Experiment Device (BEST) project is bustling with activity. BEST is expected to be completed in 2027 and demonstrate fusion power generation for the first time in the world. ”Yan Jianwen, Chairman of Fusion New Energy (Anhui) Co., Ltd., told the research team. In the 1970s, China planned to build a large-scale thermonuclear experimental facility in Hefei that was at the forefront of the world at that time. An important reason for choosing Hefei is that the Institute of Electrical Engineering of the Chinese Academy of Sciences has built a large energy storage inductance device in Hefei in the 1960s, which can provide support for the powerful pulse power supply of thermonuclear fusion devices. ”Ye Hualong, secretary of the Youth League of the Institute of Plasma Physics of the Chinese Academy of Sciences Hefei Institute of Physical Sciences, told the research team that the Tokamak experimental device carrying the Chinese people's original dream was named "Device 8". In the 1990s, the older generation of scientists exchanged jeans, porcelain and other daily necessities for the Soviet semi superconducting tokamak device and fundamentally modified it. Academician Wan Yuanxi led the team to promote the spirit of "creating conditions without conditions", and successfully manufactured various key components and equipment in a rudimentary laboratory, with a project self research rate of over 90%. In recent years, the steady-state long pulse high confinement mode plasma has run from 100 seconds to 400 seconds and then to 1000 seconds, completely maintained by China's magnetic confinement nuclear fusion team. Technological innovation is like a prolonged relay race, with a series of innovative breakthroughs from 0 to 1 driven by the patience of researchers and the empowerment of policies. In 2016, the State Council issued the "13th Five Year Plan for National Science and Technology Innovation", which clearly proposed to "build a national comprehensive science center based on areas with concentrated large scientific facilities such as Beijing, Shanghai, and Anhui", and the construction of Hefei's large scientific facilities entered the "fast lane" from then on. In the construction of large-scale scientific facilities with large investment and long cycles, Hefei not only "willing to spend money", but also established Hefei Future Science City Construction Investment Co., Ltd., adopting a "turnkey project" approach to build a science and technology innovation platform on behalf of scientists, allowing them to focus solely on research. The research team has learned that there are currently 13 large scientific facilities under construction and pre research in Hefei, of which 9 are located in the future large science city. On this 19.2 square kilometer land, a number of large scientific device projects such as advanced light source "big eyes", lightning protection "golden bell cover", and compact fusion "small sun" are densely arranged and constructed, giving rise to one "from 0 to 1" continuous emergence. The terahertz security inspection imaging system we have developed is one of the 'golden eggs' derived from large scientific devices. ”Wang Hongbei, General Manager of Anhui Zhongke Terahertz Technology Co., Ltd., said. Anhui Zhongke Terahertz Technology Co., Ltd., established in 2019, is based on nuclear fusion technology and has successfully transformed scientific research achievements into productivity. It has successfully developed multiple high-tech products with proprietary intellectual property rights, such as active terahertz human imaging security inspection equipment, terahertz laser transmission imaging system, terahertz digital CT, etc. Terahertz is just one of the detection technologies derived from fusion. We have made a preliminary estimate that if we invest 10 billion yuan in controllable nuclear fusion, it can bring about an upgrade and iterative development of the entire industry chain worth 100 billion yuan, "Kong Defeng, head of the Fusion Center at the Energy Research Institute of Hefei Comprehensive National Science Center, told the research team." The industry chain and technology chain involved are very long and complex, not only high-tech content, but also high net worth industries At the same time, like "picking a cake on flat ground", China's third-generation autonomous superconducting quantum computer "Benyuan Wukong" has been launched and operated in Hefei, and the 504 bit superconducting quantum computing chip "Xiaohong" has broken records... The Yunfei Road in Hefei High tech Zone is also known as the "Quantum Avenue", gathering more than 30 leading quantum technology enterprises along the way, covering the three major fields of quantum computing, communication, and measurement, forming the most dense quantum industry ecosystem in the country. However, more than 10 years ago, this was still a piece of farmland in the suburbs of Hefei. As an important source of innovation and development in quantum technology, Hefei has gathered nearly one-third of the country's quantum technology enterprises, with more than 70 upstream and downstream enterprises in the city's quantum industry chain, ranking first in the country. Lv Bo, Deputy Director of Hefei Science and Technology Bureau, said that Hefei has initially built a complete quantum ecological chain from basic research and core technology breakthroughs to engineering and industrialization. In 2009, when Keda Guodun Quantum Technology Co., Ltd. was established, it did not attract much attention. Subsequently, they undertook the major scientific and technological project of building the "Quantum Communication Experimental Demonstration Network" in Hefei city. Based on this project, we have built the world's first quantum communication network, and the company's technology has been transformed from a discrete prototype in the laboratory to a prototype with certain industrial functions, "said Zhou Lei, Vice President of Guodun Quantum. Afterwards, the construction of the "Beijing Shanghai Mainline" for quantum secure communication and the launch of the "Mozi" quantum satellite all began with the accumulation of technology and applications in the early stages. Nowadays, the number of quantum encrypted communication users integrated by Guodun and China Telecom technology has reached nearly 6 million. (New Society)
