Peixue Wu

I’m currently a Postdoc at the Institute for Quantum Computing at Unversity of Waterloo, supervised by Graeme Smith. Before I joined Institute for Quantum Computing at Unversity of Waterloo, I obtained my PhD in mathematics 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 and probability theory. In particular, I am interested in problems related to open quantum systems and quantum capacities.
