Peixue Wu

 

I’m currently a Postdoc at the Institute for Quantum Computing at Unversity of Waterloo, supervised by Graeme Smith. I obtained my PhD in mathematics at University of Illinois Urbana-Champaign advised by Renming Song and Marius Junge in 2023. My thesis title is Dynamical approach in quantum information theory. My research interest is quantum information theory, noncommutative analysis and probability theory. In particular, I am interested in problems related to open quantum systems and quantum communications.
