Abstract
In this research project we will study methods of protection and optimization of quantum logic gates in quantum dots, in order to enable quantum simulation in these devices. Our main objective is to develop efficient and realistic strategies to protect information and quantum gates against the deleterious effects of the environment. We will study defensive strategies based on (i) dynamic decoupling and (ii) quantum optimal control. Based on our recent studies, we will explore these techniques to include physical systems consisting of many levels of energy (qudits) and also many parts (chains of spins). We will determine and compare the effectiveness of these two different control methods and we will concatenate them in order to increase the protection efficiency. Our final goal, in this sense, is to apply such methodology to the application in quantum simulation, mainly in the study of Hubbard model and the simulation of controllable chemical reactions. (AU)
