Biography

I am a quantum information theorist, currently an assistant professor at the University of Hong Kong.
From 2018 to 2021, I worked at ITP, ETH Zürich (Renato Renner's group) as a postdoc.
I obtained a PhD in Computer Science from the University of Hong Kong (2018; supervisor: Giulio Chiribella) and a Bachelor in Physics from Tsinghua University (2013).

My research interests include:

• Quantum Metrology: ultra-precise estimation using quantumness
• Quantum Information: entropies, communication, and beyond
• Quantum Computing: fundamental requirements on implementing quantum computation
• Quantum Foundations: the interplay between information and laws of the universe

Openings

I am looking for motivated PhD students.
Please email me with your CV, publications (if any), transcript, and a brief statement of interest.
