Functional Analysis and Quantum Information

Dates: 20-24 March, 2023

Contact: Fernando Lledó (, Carlos Palazuelos (, Julio de Vicente (

In recent years there have been many interactions between quantum information and functional analysis, which have led to striking results in both fields. The aim of this week is to go deeper in this direction by discussing some of the most recent results and also by thinking about new interesting open problems. Along the week, there will also be some talks adding quantum field theory as another interesting ingredient to be considered in the interface between quantum information and functional analysis.
