Eighteen since five years, all cadres and workers, ningxinjuli, and seek common development, with wisdom and sweat to create 14 new development speed, seize a new victory. Five years of inspiring achievement, landing a major project, a key project to promote scientific and technological innovation, a breakthrough, get a flash medal...... The grand blueprint has been painted, and the bugle has sounded. We should follow the "five class" development goals, emancipate the mind, innovation, firm belief, overcome difficulties, forge ahead, go ahead, and strive to 14 in the reform and development of various undertakings continue to move forward, and strive for the efforts to achieve domestic excellence, world-class innovation leading group with outstanding achievements to greet! The party's nineteen big victory is held!
Endeavour temper for five years -- a major technological breakthrough article
These are still fresh sense of the screen, will become the most classic memories of the quantum team mind: "wind like knife cut my face, and so on, can not wait until the west sea blue sky."......" In 2015, at the beginning of November, Jiangnan or the most beautiful autumn season, the Northwest has winter, this song is a true portrayal of the natural environment in Haibei plateau in winter. But for the members of the quantum radar team, the cold wind is no big deal, and what worries them most is the sudden two hours of blackouts before acceptance.
Different from other fields, quantum near infrared detection belongs to 14 new areas, the environment demand is special, no reliable field security equipment, no mature base can rely on, so from the power supply, protection to personnel accommodation, meals are in need of project team head arrangement, test site you must first reach an agreement with the local villagers, from the beginning of "chop and burn the raft, luxuriant vegetation Mao" opened up a space in a small hill. Power line quantum radar test equipment the main power supply from an abandoned small kiln, usually in power project to prepare the homely food, a small generator standby, but before acceptance, due to failure to shut down the generator.
Acceptance only quantum radar principle prototype at night, after sunset in Haibei plateau colder, project acceptance of the expert group of the county rushed to the hotel to rest, immediately contact the relevant units, and the night finishing equipment in experimental class, ready to resume testing. Finally, at about 12 in the evening, the electricity was restored. The morning of the 6 field, cold, quiet, quantum radar transmitter is rotating slowly, 20 kilometers, 50 kilometers outside the target to be detected, then, a turntable steering angle, displayed on the screen in the hundreds of kilometers outside the position suddenly detected clear signal, the first domestic power breakthrough hundred kilometers the same type of radar prototype through the acceptance of!
The process of acceptance of small twists and turns, just a little story of quantum field work in radar team, in recent years, the team started from the theoretical analysis, through in-depth exploration research, successfully developed quantum radar remote detection prototype, but also overcomes the security conditions, hypoxia and a series of difficulties, the completion of the remote detection field test in Qinghai lake, has been highly appraised the acceptance of the expert. In the next year, the team used spurious quantum radar technology, the quantum radar can work in the daytime, and can track the slow moving target, and completed the long day sea environment test in Qingdao.
In order to meet the needs of the future battlefield, the sensitivity and accuracy of radar must be higher and higher, but the limitation of the natural law will lead to the development of radar technology. The laws of microscopic nature are described by quantum physics, and quantum fluctuations of the electromagnetic field can obscure tiny objects. In order to be able to detect, measure and even identify very weak targets in the quantum world, it is a problem for the radar detection field to make full use of quantum resources for detection.
In plateau lake, our quantum radar research team conducted remote detection experiments on quantum radar prototype, broke through the limit of detection of similar radar, radar remote for the first time in the international level of quantum detection. In 2016, caps, an American think-tank, quoted the research progress of China's quantum radar team, pointing out that China has completed the remote test of the quantum radar prototype and came to the forefront of the world.
