Abstract In this project, we will investigate reset protocols, which are an important step in the developmentof quantum computing. We aim at engineering new reset protocols, in addition to optimizing theparameters of each protocol, in order to obtain a faster erasure of information. Thus, we willanalyze both weak and strong coupling regimes for interactions of quantum systems to discoverthe set of parameters and conditions that accelerate the redefinition of the states of the qubits.We also intend to study the energy cost necessary to erase a certain amount of information,for that we must know the dynamics of the entropy and heat changes of the discussed systems.These two quantities can be related through the Landauer's principle, which predicts what is theminimum energy related to the process of erasing a bit of information. Furthermore, we willanalyze the principle's validity for correlated systems. As a main research object, during this partof our project, we will numerically solve the dynamics of qubits's chains in different topologies. | |
