“Recently one of our important results is about to published in the journal” Nature “, this is my results of schematic design for the cover of the magazine.” January 4, New Year’s a weekday afternoon, the newly elected Chinese Academy of Sciences China the Science the technology University Professor Pan Jianwei open image file in his office on the computer, happily told reporters.

been Daily named the top ten science newsmakers Pan Jianwei, the youngest one in the 2011 annual new academicians. Since 1997, he and his team have “natural” and “Nature Physics” Nature Photonics “” United States Proceedings of the National Academy of Sciences “,” Physical Review Letters international authoritative academic journals and papers 67, 7500, the results of five-time European Physical Society named “the year significant progress” in Physics, 4 times selected for the American Physical Society named the “annual major event in Physics 6 times selected for the selection of academicians of China Top Ten Advances in Science and Technology News “. Because of the systematic work carried out by Pan Jianwei and his team in the field of quantum information experiments, they were the international authority of the Physics Review magazine, “Reviews of Modern Physics” and “physical address” invited to write about multi -photon quantum entanglement manipulation and quantum communication experiments review papers, including the former China mainland scientists in the journal published the first experimental review papers.

quantum world is fascinating and inspiring

choose physics as their professional, completely out of the Pan Jianwei’s interests and hobbies. In 1987, Pan Jianwei, was admitted to the Department of Modern Physics of USTC. College, class, only the province of college entrance exams, 7. Results can only be considered lower-middle, but I am a good attitude, learning has been very positive, a keen interest in physics homework per door. “Pan Jianwei said with a smile, because I like, so there is enthusiasm, patience, the case to the frustration, but also comfortable with.

accordance with the theory of Newtonian mechanics, the objective world is like a huge machine, the nature of all material like the parts of the machine, its law of motion and interaction solely by the laws of mechanics to dominate, so the whole world of the future direction of and development trends is also determined by the laws of mechanics. Newtonian mechanics has opened up a human understanding of the objective world a new era of , “said Pan Jianwei, but quantum theory is that the material simultaneously in multiple possible states of the superposition state when being observed or measured, will randomly show a certain state. “Ghostly array run to the physical form of the arrival and leave,” This is the general form of the existence and evolution of the material revealed by quantum mechanics.

“in the view of quantum mechanics, the” observation “of the people is the key to the transformation between the indeterminate quantum world and established reality.” Pan Jianwei said, “from a philosophical perspective, quantum mechanics is a positive science, fascinating and inspiring. personal struggle is therefore a positive significance, if a person is in the “success” and “failure” of the superposition state, the personal struggle to make him Chaozhu probability of success of state evolution. “

in 1996

, the USTC get a master’s degree in Theoretical Physics, PAN Jianwei has been studied under doctorate its investment in the University of Vienna, Austria Salinger professor. In that time, the tutor is organizing a few million euro EU project, which is the first experimental study of quantum information, an international cooperation project. Previously, quantum information has been in the phase of theoretical research, there is no experimental support. “I better theoretical foundation, so soon into the state work very fast.” In 1997, a research paper entitled “Experimental quantum teleportation,” published in “Nature” magazine, the results are recognized as pioneer the field of quantum information experiments, while the European Physical Society and the American Institute of Physics will be named the world’s physics the year significant progress, the United States “Science” magazine the the annual Worldwide top ten scientific and technological progress. Later also in the work of Nature magazine as the “century of physics 21 classic paper” one.

“I am the second author of the paper, published experimental data measurement and processing is completed.” Pan Jianwei said, “this work as a starting point, the experimental study of quantum information has since entered the popular state.”

this year, Pan Jianwei, just 27 years old.

we must first sharpen his

doctorate of the University of Vienna in 1999, Pan Jianwei, ready to return to work, but to apply for research funding has not been approved. “At that time, the quantum information research in the country there is much controversy, some people even think that is a pseudo-science. Until our paper appeared in the” Nature “magazine century classic, this support began to increase.”

in 2001, the Pan Jianwei research project application is approved, back to the USTC work. Quantum information research and development soon, when either the level or the talent pool, domestic fundamentals are weak. “We must keep in close touch with the international advanced group, with an open mind to learn from them in order to move a lot faster. If you wait until the others running away, you stop chasing too late.” Pan Jianwei said.

under the guidance of this line of thinking, Pan Jianwei, Professor Yang Tao and his students an organized research team to carry out laboratory building at the same time, also continued at the University of Vienna in collaborative research in the multi-photon entanglement. “Results in the year 2003 alone,” Physical Review Letters paper published by the domestic group as the first unit there are seven. “Recalls Pan Jianwei.

2004, Pan Jianwei, Research Group in the international arena for the first time the five-photon entanglement and open-destination quantum state teleportation, “Nature” magazine published the results, and praise, said: “This novel quantum teleportation the key technologies needed for quantum error correction and distributed quantum information processing. “This achievement is named to the significant progress of the European Physical Society and the American Physical Society selected the annual International Physics, Chinese scientists is the first time.

“This shows that the domestic research team has successfully leapt to the international advanced level in the aspects of quantum entanglement.” Pan Jianwei said, “I left Vienna, where the knowledge of our national team has got hold of all.”

Since then, the Pan Jianwei, to the identity of the Marie Curie Chair Professor to the University of Heidelberg, Germany, engaged in collaborative research in quantum storage. “To achieve high efficiency, the long-distance quantum communication, quantum storage and quantum relay technology, cold atomic ensemble is the ideal system for quantum storage.” Said Pan Jianwei, “University of Heidelberg cold atoms in a leading international position, we have to put someone else’s special skill Xuedao Shou. “

a few years, the Pan Jianwei, team formation in cold atomic weight of sub-storage with a wealth of talent and technology accumulation, made a series of leading international research. In 2008, “Nature” magazine published Pan Jianwei, team research, they use quantum storage technology in the international arena for the first time the entanglement swapping with the storage and readout functions, the perfect realization of the urgent need for long-distance quantum communication “quantum repeater”. “Nature” magazine praised the work “has removed a major stumbling block in quantum communication”. The results of selected significant progress of the European Physical Society annual physics. They are also the first time quantum teleportation between photon-bit and atomic bit, for the first time single-shot quantum storage life extended to the millisecond, the previous results to improve by two orders of magnitude.

we must first sharpen his. Maintain close cooperation with the international advanced group, continue to learn from each other, the secret of Pan Jianwei team to the rapid development and growth.

biggest dream

October, 2008, Pan Jianwei and his team in Germany, the overall regression USTC. “Move list a full list of 120 large to lasers as small as 12 mm lenses, all to move back.”

this time

, Pan Jianwei, the team has become an international for the first time the security of quantum communication distance to break through to one of the more than one hundred kilometers of the order of three teams, international safety reports on the practical the quantum the communication network one of the two teams in the experimental study is also the only lead the research team to carry out the experimental study of the satellite and the ground quantum communication. “New Scientist” commented Pan Jianwei, team: “(They) make USTC, and thus the whole of China, occupies a place firmly on the map of the world of quantum computing.”

“In the light quantum entanglement manipulation and quantum communication, we eventually reached the position of leader we can to carry out the work of leading international research in the country.” Pan Jianwei said.

quantum information set multi-disciplinary one, in order to achieve a breakthrough, you must have the background of the personnel of different disciplines. These years, in order to carry out quantum information plate “dishes”, Pan Jianwei, has been in the reserves of a variety of “raw materials”, the background of the young people of different disciplines, sent abroad, distributed to Germany, Britain, the United States, Switzerland, Austria and other quantum information research of outstanding international group to exercise.

In recent years, been deliberately “flying abroad for many years, young people, as the kite income line, the full return, USTC team has been unprecedented growth. Professor of the laboratory alone, “Youth thousands of plans,” “Hundred Talents” to 10. They are basically better than my 10-year-old is now in the creation of the peak period. “

it comes to the team’s focus on the development of future direction, Pan Jianwei, column two: First, the wide-area quantum communication to further advance towards practical; the development of quantum simulation techniques developed quantum manipulation in turn, promote quantum physics and condensed matter physics, basic research. “This will enable quantum science and technology between the formation of benign positive feedback, this is what I am most happy.”

in April 2009, Pan Jianwei team in Hefei, the world’s first light quantum telephone network to achieve a “telephone interconnection, voice, real-time encryption, security unbreakable” quantum confidential telephone network system. Two years, the light quantum telephone network in system miniaturization and stability have made rapid progress.

“quantum cryptography MAN has been basically mature faster then two or three years, slow three to five years, it can be extended.” Pan Jianwei said, “but to achieve a wide area of ​​quantum cryptography communication, but also almost no loss for the photon quantum information carriers in the spread of outer space, if we can technically entangled photons to penetrate the entire atmosphere is still alive and maintain their entanglement properties, people can satellites help needs via satellite. globalization of quantum communication.

“Chinese Academy of Sciences has launched a strategic lead science and technology projects of space science, quantum science experimental satellite plans to launch around 2015.” said Pan Jianwei, his mentor, Professor Salinger learned to launch quantum satellite, made a special trip to China twice, and I hope to be able to cooperate in this work. “Not long ago, Salinger, Professor and President of the Austrian Academy of Sciences a visit to the Academy of Sciences, signed a cooperation agreement intercontinental quantum key distribution with us. Just 70 years old in 2015, my mentor, he said that to accomplish this very important experimental challenge is the last wish of his life. “

“Many people ask me what is my dream? I said, the dream is not what you want to get something, but you found a very wonderful thing, you want to do just so.” Pan Jianwei said, on the basis of quantum communication technology development in the current to the extreme, which is both beneficial to the country and the nation, but also to satisfy my own curiosity, which is the most pleasant thing, for me, is my biggest dream “(Wuchang Feng)
