The picture shows the physical picture of optical quantum interference of Quantum computer in "Chapter Nine". On September 4, 2022, in Beijing, a representative of a participating enterprise introduced quantum encryption intercom at the 2022 National Cybersecurity Promotion Week Cybersecurity Expo. Liu Junxi, a reporter from Xinhua News Agency, photographed the model of the programmable quantum computing system "Zu Chongzhi" at the "Endeavour for a New Era" themed achievement exhibition held in Beijing on November 4, 2022. The picture (people's vision) taken by Chen Xiaogen is a popular science picture that introduces the use of Quantum computer. Recently, a news about quantum technology has attracted social attention. After completing the preparation of 10 bit, 12 bit, and 18 bit true entangled states since 2017, Chinese scientists who have been at the forefront of quantum technology have recently set a new world record - successfully achieving the preparation and verification of 51 superconducting quantum bit cluster states, breaking the world record for the number of true entangled bits in all quantum systems, and demonstrating the first measurement based variational quantum algorithm. From "Mozi" flying to space to the successful development of Quantum computer, today, China's quantum technology has achieved a historical leap from following and partly leading. Quantum communication research has steadily taken the lead in the world, quantum computing research has firmly established its international first position, and quantum precision measurement research has entered the international leading ranks in many directions. This also means that China's development is accelerating in the "Dark Blue" technology fields such as "heaven and earth integration" and Big data. All this is inseparable from the research team of Pan Jianwei, academician of the Chinese Academy of Sciences Quantum information and Quantum Technology Innovation Institute, University of Science and Technology of China (USTC). Academician Pan Jianwei is mainly engaged in the research of Quantum optics, Quantum information and the inspection of basic problems of quantum mechanics. As one of the pioneers in the field of Quantum information experimental research in the world, he is a scientist with important international influence in this field. By means of Quantum optics, he has made a series of significant research achievements in the field of quantum control. In particular, his systematic innovative work on quantum communication and multi photon entanglement manipulation has made Quantum information experimental research one of the fastest developing directions in physics in recent years. The quantum leap has a promising future. It is the dream of Academician Pan Jianwei's team to use quantum research to help the great rejuvenation of the Chinese nation. It is the unremitting pursuit of this dream that makes Pan Jianwei and his team become the world leader in the field of quantum communication. The quantum dream originated from serving the country on December 18, 2018. At the conference to celebrate the 40th anniversary of reform and opening up, Pan Jianwei was awarded the title of "reform pioneer". When communicating with college students, Pan Jianwei talked about his youth. In 1987, at the age of 17, Pan Jianwei was admitted to the Department of Modern Physics at the University of Science and Technology of China. Here, Pan Jianwei learned many touching stories of technological predecessors. Pan Jianwei said to the college students, "Many foreigners don't understand why China was able to accomplish the feat of" two bombs and one satellite "because the conditions were so poor at that time. It is precisely because a large number of scientists with family feelings have contributed everything to the country's scientific and technological cause." At the University of Science and Technology of China, Pan Jianwei was criticized by the quantum theory
