There are many advanced technologies in China, the most representative of which are \/5G communication, laser manufacturing technology and quantum information technology.
1, 5G communication technology Needless to say, the future will change our lives technology. Some people may say that the current 4G is enough and 5G is not needed. It is also true that the application scenario of 4G is the Internet of people, and the 5G application scenario is the Internet of Things, such as the automatic opening and closing of doors and Windows at home, and the automatic driving of vehicles on the road, etc., all need 5G technology. 5G technology can profoundly change the future of life, and it can also change the face of future war. For example, 5G communication technology will make it possible for the military to have a dedicated frequency, which will effectively solve the current problem of overlapping frequency bands and mutual interference between military mobile communication systems and civilian mobile communication systems. 5G communication technology will promote the interconnection of battlefield all-area weapon platforms, and the application of this technology will be able to connect all weapon platforms equipped with 5G communication modules into a network in the battlefield area. Based on this, all kinds of troops on the battlefield can not only realize the interconnection of battlefield information terminals, but also realize barrier-free communication. 5G communication technology will realize the deep integration of battlefield information networks, and 5G communication technology will provide the military with a wide-area coverage, high-speed transmission, and strong compatibility of air-ground integrated information communication network, thus greatly improving the information support and support capability of the battlefield.
2, laser manufacturing technology we may be relatively unfamiliar, in 2000, the Chinese laser research group will be laser technology applied to 3D printing technology above, laser welding greatly improve the success rate of 3D printing technology. At the same time, 3D laser welding technology solves a lot of problems in the world, and can produce more complex works. Now China has been able to use laser welding technology to produce more than 12 meters of large titanium alloy components, becoming the world's largest in this field. By now, many of China's advanced fighter jets are made of titanium alloy components made by 3D laser welding technology, which is already a fifth of all parts. China's civil aircraft have also begun to use this technology, which can greatly reduce the cost of replacing aircraft parts. The structure of the domestic large passenger jet c919 is the use of laser technology to manufacture titanium spars, and China has occupied a high position in this field in the world.
3, quantum information technology is a very fashionable technology, mainly including quantum communication and quantum computing two fields. Quantum communication mainly studies quantum cryptography, quantum teleportation, long-distance quantum communication technology, etc. Quantum computing mainly studies quantum computers and quantum algorithms suitable for quantum computers. At present, China maintains the world's leading level in this field. Quantum computers could allow China to create the world's fastest supercomputer. In May 2017, China announced the successful development of a quantum computer, although this quantum computer only 50000 times per second addition operations, even compared to ordinary engineering computers, but it is hailed as \"one of the new scientific and technological achievements that can change the world in 2017.\" The computer was able to create 10 superconducting qubit operations, while the United States could only maintain a maximum of nine, a full decade ahead of the United States. Quantum communication satellite is a kind of communication satellite with efficient transmission, which can improve the security of Chinese-made satellites. If quantum technology is used for communication, it is impossible to breach with the current human technology, and the security is guaranteed, and the secret communication technology that prevents eavesdropping and cracking by spies is completely eliminated, so as to contend with foreign network attacks and defense capabilities.
American scientist Peter Heuer proposed the \"quantum algorithm\
On January 18, 2017, the world's first quantum science experiment satellite \"Micius\" was officially delivered to the University of Science and Technology of China after successfully completing a 4-month in-orbit test mission. On June 16, 2017, China's \"Micius\" quantum satellite achieved quantum entanglement on the order of 1,000 kilometers for the first time in the world, which means that quantum communication has taken a big step toward practicality. On September 29, 2017, the world's first quantum secure communication trunk line \"Beijing-Shanghai Trunk Line\" and \"Micius\" scientific experiment satellite conducted a link between heaven and earth, and Chinese scientists successfully realized intercontinental quantum secure communication. This marks that China has built the first prototype of an integrated wide-area quantum communication network in the world, and has taken a solid step toward realizing a quantum secure communication network covering the world in the future.
