The Quantum Technology Research Team of the University of Science and Technology of China, led by Academician Pan Jianwei, recently published the latest research results, achieving the first ten-photon entanglement in the world, and once again refreshing the world record of photon entanglement preparation. This is also the team's re-created world record after the launch of the quantum science experimental satellite this year. Although he has become a leader in the field of quantum in the world, Pan Jianwei is still very humble. He said: "At present, our country has only one or two points in the forefront of the world, and we dare not say that it is leading. It takes 10 to 20 years for quantum technology to reach the internationally recognized leading position." Pan Jianwei speaks at Mozi Salon Previously, the Baguangzi record was also created by members of the research team of Lu Quanyang and Chen Yuxi, the quantum technology research team of the University of Science and Technology of China led by Academician Pan Jianwei, and maintained for 4 years. The team's "Multiphoton Entanglement and Interferometry" won the first prize of the National Natural Science Award last year and became the youngest team in history to receive this honor. As the core index of the basic ability of quantum information processing, multi-particle entanglement manipulation can be systematically applied to many research directions such as quantum communication and quantum computing, and has always been the focus of international competition. The research results will also be applied to large-scale quantum information technology. "Multi-photon entanglement", as the name suggests, is to make multiple photons entangled, which is a necessary precondition for the use of photons for quantum teleportation and quantum computing. "Entanglement" in quantum mechanics refers to a superposition of multiple particles. When two particles are entangled, a superposition of two particles is formed, which is an "entangled state". In the absence of external interference, no matter how far the two particles are apart, the entangled state can exist. Therefore, quantum entanglement was once called "spookyacTIonatadistance" by Einstein, and it is used to question quantum mechanics. Completeness (because it violates his "locality" principle). However, each experiment later confirmed the correctness of quantum mechanics. Non-localized quantum entanglement can exist, and the principle of locality must be discarded. Zhang Wenzhuo, an associate researcher at the Center for Excellence in Quantum Information and Quantum Technology of the Chinese Academy of Sciences and the Shanghai Research Institute of the University of Science and Technology of China, said in response to the explanation of the First Financial Journal: "With the birth of quantum information science, quantum entanglement has become the core of quantum communication and quantum computing. ." Zhang Wenzhuo said that for the demand of quantum information processing, especially photon quantum computing, the number of entangled photons is naturally as good as possible. Experimentally, photon entanglement requires the acquisition of photons generated by photon sources through various optical interference methods. This is why "multiphoton entanglement" and "multiphoton interference metrics" have become a whole subject. The more photons that are entangled, the more complex the system of interference and measurement, and the more difficult the experiment. The method of entanglement caused by two-photon interference is accumulated and expanded to more photons, so that more photons can be formed. According to public data from the University of Science and Technology of China, the Pan Jianwei team has maintained a world record of entangled photons since 2004. In 2004, the world's first five-photon entanglement was realized. In 2007, the world's first six-photon entanglement was realized. In 2012, it was the first in the world to achieve eight-photon entanglement, and keep the record so far. Since the probability of photon generation and optical interferometry increases with the photon number index, the optical interference system is doubled for each additional entangled photon, and the difficulty of entanglement increases with the photon number index. Based on multiphoton entanglement technology, the team realized the world's first 100-kilometer quantum entanglement distribution and quantum teleportation in the field of free-space quantum communication, and realized the world's first optical quantum Shor algorithm and topological quantum in the field of quantum computing. Correction. But "multi-photon entanglement and interference metrics" is only part of the work of the academician Pan Jianwei. In 2016, the team undertook the launch of the world's first "quantum science experimental satellite", which will realize the world's first quantum security communication and quantum teleportation between the stars. At the same time, the world's first quantum security communication backbone network "Beijing-Shanghai trunk line" due to the team's technological achievements will also be completed early next year. 12W Medical Adapter,12W Breast Pump Adapter,Medical Ivd Adapter,12W Medical Ivd Adapter Shenzhen Longxc Power Supply Co., Ltd , https://www.longxcpower.com
