Quantum Engineering and Precision Measurement

With the rapid development of quantum engineering technology, people are researching how to utilize quantum effects to develop practical high-tech and explore cutting-edge basic science. In recent years, revolutionary breakthroughs have continuously emerged in the field of quantum engineering. People have been able to design, manipulate, and measure artificial quantum systems. Artificial quantum systems possess stable quantum coherence and a high degree of controllability, providing new opportunities for the understanding, manipulation, and application of quantum effects. Focusing on artificial quantum systems such as ultracold atomic gases, combining both theoretical and experimental approaches, facing the forefront of science, and in line with the country's major strategic needs for precision measurement, while studying frontier basic issues in quantum science, we explore the experimental realization of quantum simulation and quantum precision measurement.

The team is the core research team of the Key Laboratory of Quantum Precision Measurement and Sensing in Guangdong Province. Currently, the team has more than 30 faculty and researchers, including 3 professors, 7 associate professors, 3 associate researchers, 4 post-doctoral fellows, and 17 postgraduate students. The team currently has research groups such as quantum atomic optics, many-body problems of quantum gases, and low-dimensional quantum materials. It has established an experimental platform for ultracold rubidium atomic gases and an experimental platform for precision optical imaging, and is building experimental devices such as an ion trap experimental platform and an experimental platform for low-field nuclear magnetic resonance of atomic magnetometers.

The main research directions include:

  • Quantum Engineering and Quantum Simulation [ultracold atomic gases, ultracold trapped ions, low-dimensional quantum materials, quantum state preparation and manipulation, quantum simulation, quantum artificial intelligence, etc.];
  • Quantum Precision Measurement and Sensing [quantum interference, quantum parameter estimation, quantum precision measurement optimized by machine learning, precise magnetic field measurement, high-precision optical clocks, precise gravity measurement, precision optical imaging, etc.];
  • Cold Atom Physics (quantum optics, many-body quantum physics, non-equilibrium quantum dynamics, ultracold collisions, collective quantum phenomena, quantum correlations and quantum phase transitions, topological states of matter and topological phase transitions, etc.).
