-{{::​line-2-ref-2.png?​200|}} 
-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.
