The Fourth 2022 National Quantum Computing Hackathon Competition was brought to a successful end the other day. The team named "It's OK to Meet at 5:00am" made up of 3 postgraduate students of Chongqing University, including Chu Yida, Xu Wei and Zhou Yanhua, won the first place with the highest total scores after defeating tough competitors in the intense competition of over 2 months. These 3 students are all members of the team of Professor Zhang Xuefeng from the Strong Correlation Research Group of the School of Physics, Chongqing University.

As an important component of future science and technology, quantum computing is believed to have the potential to trigger the next revolution in quantum science and computer science. It may not only generate enormous economic output, but is also closely related to military security of China.  As the most important event in the field of quantum computing in China, the "National Quantum Computing Hackathon Competition" has very high prestige. Every year, teams from Peking University, Tsinghua University, the University of Science and Technology of China and Southern University of Science and Technology, and other scientific research institutions would participate in the Competition. The Competition is open to all developers. Participating teams include those made up of students led by teachers, those made up of developers of companies and overseas scientific research teams.

Looking back on the endeavors they made in the past two months, the team members said they were really a great team and attributed the success to the efforts of every team member. They added that the team members boasted that they'd rather be thrown into the trash if they won only the second place. Now they are delighted they made it.

The team of Professor Zhang Xuefeng has been focusing on quantum many-body theory for a long time. The research areas of the team mainly include strong correlation numerical calculation, quantum simulation and quantum precision measurement. In the past two years, the research team has made significant progress in strontium atomic optical lattice clocks. It has published a succession of papers in Physical Review Letters, a top journal on physics, and has been reported on the cover page of Physics.

It is reported that the Fourth 2022 National Quantum Computing Hackathon Competition is a major competition in the field of quantum computing in China. More than 500 developers from home and abroad participated in the Competition, and nearly 200 teams signed up. Developers participating in the Competition include students from more than 170 colleges and universities in China, among which there are more than 70 colleges and universities under the "Double-First-Rate" Construction Program, and more than 10 top overseas colleges and universities.
