Biography
Po Zhang received B.S. degrees in physics and mathematics from Nankai University in 2012, and a Ph.D. degree in physics from Peking University in 2017. During PhD, he studied quantum Hall states in two-dimensional electron gas in Prof. Rui-Rui Du's lab. Subsequently, he joined Prof. Sergey Frolov's lab at the University of Pittsburgh as a postdoc. He lived in Pittsburgh until 2022, studying topological states and Andreev bound states in superconductor-semiconductor (super-semi) devices. Thereafter, he joined the semiconductor quantum computing group led by Prof. Hongqi Xu at BAQIS as an associate research scientist.

Research
Po Zhang's recent research interests focus on searching for non-Abelian quasi-particles in super-semi hybrid devices and studying physics in these mesoscopic devices. Non-Abelian quasi-particles like Majorana zero modes hold great promise for realizing physically fault-tolerant qubits. The super-semi system is a nice playground for exploring the wonders of quantum or topological physics (and beyond), thanks to the sophisticated semiconductor growth and nanofabrication techniques available today. Click here for an introduction.
Po is also interested in fractional quantum Hall states (strongly-correlated topological systems) and artificial systems consisting of arrays of gate-defined quantum dots (quantum simulation).
