Introduction：
The Laboratory of Quantum Science and Engineering was established by the School of Mathematics of South China University of Technology and Wuhan Institute of Precision Measurement Innovation of Chinese Academy of Sciences on April 19, 2019, in order to promote the research of quantum science project, a major RESEARCH and development program of Guangdong Province. The laboratory has 15 members, including 7 professors and 8 associate professors.
Research Fields
l Precise quantum measurement
l Quantum Information
In the field of precise quantum measurement we focus on surface noise detection and weak alternating magnetic field detection.
In 1998，researchers found that the anomalous heating effect of ions may be due to the random change of local work function caused by adsorbents on electrode surface. Subsequent studies have shown that the noise spectral density of electric field depends on the concentration of adsorbed atoms on the surface of the trap electrode and the ambient temperature. Since the sensitivity of the trapped ions to the environment is higher than that of the current common surface measurement instruments, the trapped ions could be used as a new tool for surface science. It is also found that base on the combination of quantum phase-locked amplification and multi-ion entanglement technology, the weak magnetic field signal could be measured in the noisy environment beyond the standard quantum limit.
Our experimental work on precise quantum measurement mainly performed with ion trap system and linear optical system.
In the field of Quantum information we focus on the theoretical study and corresponding experimental simulation.
Quantum information is an interdisciplinary subject of quantum mechanics and information science. It involves quantum communication, quantum computation and quantum measurement.
We study the foundation theories of quantum information including quantum entanglement、non-locality and separability. And we also study the theories of quantum codes, quantum key distribution (QKD), quantum network and quantum machine learning (QML).
