Peng Kunchi, academician of the Chinese Academy of Sciences, was born in Zhenjiang, Jiangsu Province in August 1936, originally from Guangyuan, Sichuan. Graduated from the Department of Physics of Sichuan University in 1961.
From 1982 to 1984, at the University of Texas in the United States, he participated in the preliminary work of the world's earliest experimental research on the generation of light field squeezed states, and developed a "high-output frequency-stabilized YAG laser" in Kimble Laboratory.
In 1988-1989, he completed OPO parameter down-conversion using a double KTP crystal at the California Institute of Technology in the United States for the first time to prove quantum coherence and the EPR paradox of continuous variables.
In 2003, he was elected as an academician of the Chinese Academy of Sciences. Served as president of Shanxi University from 1991 to 2000; served as director of the Chinese Physical Society, deputy director of the Quantum Optics Professional Committee of the Chinese Physical Society, review expert of the Optics II Group of the Department of Information Science of the National Natural Science Foundation of China, and member of the second expert advisory committee of the Department of Information Science .
He is currently the director and professor of the Institute of Optoelectronics of Shanxi University, deputy director of the academic committee of the State Key Laboratory of Quantum Optics and Optical Quantum Devices, chairman of the Shanxi Physical Society, and a special member of the Optical Society of America (OSA FELLOW). Editor-in-Chief of Journal of Quantum Optics.
Since 1985, he has presided over the establishment of the Quantum Optics Laboratory (now the National Key Laboratory) to carry out experimental and theoretical research in the fields of quantum optics, quantum information and solid-state laser technology. In the field of non-classical light fields Generation and application, especially in the research of continuous variable quantum information, a series of original work has been completed, and at the same time, the research and development of fully solidified frequency-stabilized frequency-doubled Nd:YAG, Nd:YVO4 and Nd:YAP lasers have been carried out. In the early 1990s, he presided over the completion of orthogonal dual-mode compressed vacuum state light field generation experiments, and designed and developed a new YAP/KTP system. In a semi-monolithic optical parametric oscillation cavity constructed of α-cut KTP crystal, It has realized Class II non-critical phase matching optical parameter down-conversion, and used the same system to obtain two types of compressed state light fields. All technical indicators have reached the best international level at that time; it has successively developed and completed semiconductor laser (LD) pumping fully solidified single-frequency Nd: The overall level of YAG, Nd: YVO4 and Nd: YAP lasers is internationally advanced, and they have formed products that provide a good light source for non-classical light field generation and application research. In recent years, the leading research group has achieved a series of original achievements in the field of quantum information: the experiment obtained a bright EPR entangled beam, completed a continuous variable quantum intensive encoding experiment, designed a continuous variable quantum secure communication scheme, and used three-component entanglement to achieve Controllable dense coding of continuous variables. In 2004, the experiment achieved unconditional quantum entanglement exchange of continuous variables, laying a good foundation for the research of quantum networks.
The All-China Federation of Trade Unions awarded the title of "National Outstanding Educator" and the "May 1st Labor Medal", the Ministry of Personnel awarded the title of "Young and Middle-aged Experts with Outstanding Contributions", and the Shanxi Provincial Party Committee and the Provincial Government awarded the title of "Science and Technology Honorary titles such as "Meritor" and "Excellent Leading Cadre". He won the second prize of the National Natural Science Award in 2006, the second prize of the National Technological Invention Award in 2002, the Ho Leung Ho Lee Foundation Science and Technology Progress Award in 2003, the Shanxi Provincial Science and Technology Outstanding Contribution Award in 2005, and the Taiyuan Science and Technology Outstanding Award during the "Tenth Five-Year Plan" period in 2007. Contribution awards, more than 20 other provincial and ministerial awards, and 2 invention patents. Published more than 150 papers.
