Portrait of Zhongxia Shang — 尚仲夏Quantum research

About me.

My name is Zhongxia Shang (or Zhong-Xia Shang used in publications). I am currently a postdoctoral researcher at QMATH at the University of Copenhagen hosted by Prof. Daniel Stilck França. Previously, I was an HKIQST postdoctoral fellow affiliated with the University of Hong Kong (HKU). My hosts were Prof. Wang Yao and Prof. Qi Zhao. I obtained my Ph.D. degree in Physics at University of Science and Technology of China (USTC) (2024). My advisor was Prof. Chao-Yang Lu. I also obtained my B.S. degree in Physics at the School of Gifted Young, USTC (2019).

I began my quantum journey on the experimental side of quantum computing, but later shifted my focus to the theoretical side, where I have been really enjoying designing new quantum algorithms and exploring quantum advantages. In my view, the current biggest bottleneck of quantum computing is the lack of applications. I hope to make quantum computing more useful and valuable by the day we finally create a universal fault-tolerant quantum computer!
