The aim of this research area is to investigate quantum information processing and simulation of quantum dynamics through quantum annealing methods, either in closed or open systems. More specifically, we focus on the adiabatic computation approach, which aims at manipulating a slowly-varying quantum system to attain a desired target state, which contains the solution of a computational problem. Topics of interest include adiabatic algorithms and their physical implementations, adiabatic approximation in open quantum systems, and shortcut methods to adiabaticity.
