About the lab
Spin Quantum Computing Lab, led by Associate Professor Dawei Lu at the Southern University of Science and Technology (SUSTech), is at the forefront of advancing the field of quantum computing. Since its establishment in August 2017, our lab has been dedicated to realizing physical quantum computers using spins, specifically focusing on nuclear magnetic resonance (NMR) and nitrogen-vacancy (NV) centers in diamond. Our research encompasses a diverse array of quantum technologies, including quantum control, quantum simulation, quantum machine learning, quantum metrology, and quantum thermodynamics. By exploring these cutting-edge topics, we aim to unlock the full potential of quantum computing and revolutionize various fields of science and technology.
About Prof. Dawei Lu (鲁大为)
Dr. Dawei Lu is a tenured Associate Professor and Principal Investigator of the Spin Quantum Computing Lab in Department of Physics at SUSTech. Born in Tengzhou, Shandong Province in 1988, he spent 14 years immersed in the town’s rich environment. In 2003, he entered University of Science and Technology of China, where he earned the B.Sc. (2007) and Ph.D. (2012) degrees under the guidance of Prof. Jiangfeng Du. In 2012, he ventured to the Institute for Quantum Computing at the University of Waterloo, where he commenced his postdoctoral career under the mentorship of Prof. Raymond Laflamme.
In August 2017, Dr. Lu joined SUSTech as an Assistant Professor and was promoted to Associate Professor in May 2019. Dr. Lu’s research interests are primarily focused on experimental quantum computing utilizing spins. Notably, he holds the world record for controlling the largest number of qubits (12) using the NMR technology. He has published over 50 peer-reviewed papers, and has disseminated the research findings in more than 20 invited talks and lectures. He serves as an editorial board member for Frontiers of Physics, Chinese Physics Letters, Chineses Physics B, and Acta Physics Sinica.
Beyond academia, Dr. Lu finds solace in leisurely pursuits. During his spare time, he indulges in playing video games and delving into the captivating world of detective novels.
