1. Realize the teleportation of multi-free metrics for the first time
The research team composed by Pan Jianwei and Lu Chaoyang of the University of Science and Technology of China successfully realized the teleportation of the multi-free metric sub-system for the first time in the world. The results were published in the journal Nature in the form of a cover title. This is another major breakthrough made by scientists in the field of quantum information experimental research after 18 years of the realization of the single free metric invisible state in the world in 1997. It has laid a foundation for the development of scalable quantum computing and quantum network technology. solid foundation.
Professor Wolfgang Tittel, an international quantum optics expert, wrote in the same issue of Nature in the same period: "This experiment has taken an important step towards understanding and demonstrating one of the most far-reaching and most puzzling predictions of quantum physics, and can serve as a future quantum network. A powerful basic unit." The achievement has been awarded the "2015 Major Breakthrough in Physics" by the European Physical Society.
2, Beidou system global network first star launch successfully
On March 30, 2015, the first satellite of Beidou System's global network was successfully launched in Xichang, marking the launching of China's Beidou satellite navigation system from regional operation to global expansion. Developed by the Shanghai Microsatellite Engineering Center jointly established by the Chinese Academy of Sciences and the Shanghai Municipal Government, this satellite is China's first new generation of Beidou navigation satellite. After the orbit, it will carry out test verification of new navigation signal system and inter-satellite link.
This satellite has achieved a number of pioneering efforts: the first use of the Chinese Academy of Sciences navigation satellite dedicated platform, the first use of the expedition No. 1 upper level direct in-orbit launch mode, the first verification of phased array inter-satellite links and autonomous navigation system, the first large-scale use of localizers The components are autonomously controllable.
Due to the integrated design method, according to the functional chain design concept, the whole star is divided into functional chains such as payload, structure and thermal control, electronics and attitude rail control, which greatly improves the reliability and functional density of the system.
3, "Long March 6" first flight "one arrow and more stars" record
At 7:01 on September 20, 2015, China's new launch vehicle "Long March 6" was fired at the Taiyuan Satellite Launch Center and successfully sent 20 tiny satellites into space. The successful launch of the mission not only marks the addition of new members to the Long March series of carrier rockets, but also creates a new record for China Aerospace's multi-star launch.
The "Long March 6" carrier rocket made its first flight and was launched with the launch of China Aerospace Science and Technology Corporation, National Defense Science and Technology University, Tsinghua University, Zhejiang University, Harbin Institute of Technology and other units to develop No.1, Hope No.2 and Tiantuo No.3. 20 microsatellites such as Naxing 2, Pixing 2 and Lilac 2 are mainly used for space experiments such as aerospace new technologies, new systems and new products, and promote the development of microsatellites and test verification of new technologies in China. It is of great significance.
4, the first domestic large aircraft off the assembly line
On November 2, 2015, China's self-developed large-scale passenger aircraft C919 first aircraft was officially launched in Shanghai. C919 aircraft independent innovation has five signs, including the overall aircraft program, aerodynamic shape, aircraft body design and manufacturing, system integration and project management.
For the aerodynamic layout, structural materials and airborne systems, the developers realized the large-scale application of advanced materials on domestic civil aircraft for the first time, and the parallel development of millions of components and airborne systems. In the process of integrated innovation in research and development, nearly 200,000 people participated in R&D and manufacturing in the entire industrial chain. The new technologies, new materials and new processes adopted by the company have stimulated the development of China's economy and science and technology, the progress of basic disciplines and the development of the aviation industry.
Industry experts believe that the C919 final assembly line has far-reaching significance for the development of China's civil aircraft industry, the enhancement of basic industrial strength, and the development of manufacturing power. According to plan, the aircraft will fly for the first time in 2016.
