Abstract From October 13 to 17, the "2013 Diamond Color Center Quantum Information Seminar" (QDiamond 2013: Workshop on Quantum Information using NV Centers in Diamond) was hosted by Professor Du Jiangfeng from the School of Physics. This event was supported by multiple international institutions and brought together over 70 academic groups from both China and abroad. Experts and scholars working in the fields of quantum manipulation and precision detection of diamond color centers attended this important gathering. Zhang Shou, Director of the National Natural Science Foundation of China, also made a special visit to the university to participate in the conference.
During the conference, more than 20 international experts delivered talks, sharing the latest advancements in experimental and theoretical research across areas such as quantum information processing, quantum optics, and nanoscale spatial sensitive detection. Participants exchanged insights on recent breakthroughs and discussed future directions for the field.
Professor Joerg Wrachtrup from the University of Stuttgart, Germany (recipient of the prestigious Leibniz Award in 2011), gave a presentation titled “Precision Quantum State Preparation: From Optimal Control to Error Correction.†Professor Dmitry Budker from the University of California, Berkeley, presented on “Magnetometry and Other Fun Things to Do with NV Ensembles.†Additionally, Professor Liu Renbao from the Chinese University of Hong Kong shared his work on “Exploitation of Central Spin Coherence for Sensing and More.â€
Throughout the event, participants had the opportunity to tour Dr. Du Jiangfeng’s spin magnetic resonance laboratory. The advanced scientific instruments and rapid progress in research at the lab impressed the visiting experts. Many expressed great interest in the performance of the equipment and expressed their desire to strengthen future collaborations in scientific research.
The nitrogen-vacancy (NV) center is a unique paramagnetic luminescent defect in diamond, known for its ultra-long coherence time at room temperature—on the order of milliseconds. It can be manipulated through photodetection and magnetic resonance, making it an ideal platform for quantum single-spin systems. The development of new techniques based on NV centers holds significant potential for applications in nanoscale magnetic, electric, and temperature sensing.
This conference marked the annual meeting of the International Symposium on Diamond Color Center Quantum Information. It was also the first large-scale academic seminar held in China in this field. Supported by the Ministry of Science and Technology, the Chinese Academy of Sciences, and the National Natural Science Foundation of China, the event played a crucial role in promoting research and technological innovation in diamond-based quantum systems and precision measurement. It provided a valuable platform for international academic exchange and laid the foundation for long-term scientific collaboration.
