Optimization and application of the quantum adiabatic theorem, and the quantum origin of classical interference
(Universidade Federal de São Carlos, 2022-03-29)
In this master’s thesis, we developed three different topics. In the first topic, we studied the quantum adiabatic brachistochrone method (QAB) for optimizing adiabatic dynamics. In the first part of this study, we reported ...
Blockade and antiblockade effects with near-ground state neutral atoms
(Universidade Federal de São Carlos, 2022-09-06)
In this work we study the photon blockade and antiblockade effects in a system of neutral
atoms with a two-level structure, in the limit where induced dipole-dipole interactions
mediated by light are relevant. Such system ...
Efeitos de dimensionalidade em perovskitas de haletos para aplicações em células solares: um estudo ab initio
(Universidade Federal de São Carlos, 2022-10-07)
The structural stability and toxic lead are known obstacles to the current photovoltaic application of perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs). Herein, we perform a systematic study ...
Método de dinâmicas efetivas aplicado na análise da interação qubit-qubit em dispositivos supercondutores: a interação qubit-qubit no contexto da computação quântica
(Universidade Federal de São Carlos, 2022-02-23)
In this dissertation, we approach some aspects of quantum computing. At first, we detail the Deutsch-Jozsa algorithm and show how to implement it in real IBM quantum computers, available free of charge via remote access ...
Estudo do modelo de Hubbard bidimensional não homogêneo via teoria do funcional da densidade
(Universidade Federal de São Carlos, 2021-07-14)
We implemented the DFT calculation through the Kohn-Sham formalism adapted by the methodology μ-BALDA for the inhomogeneous two-dimensional Hubbard model, which is also implemented experimentally on an ultra-cold atom traps ...
Estudo de algoritmos quânticos para resolução de equações diferenciais parciais
(Universidade Federal de São Carlos, 2022-05-02)
With great impact in various areas of engineering and mathematics, quantum computing is an emerging technology with one of its applications in resolving large-scale mathematical problems, such as optimization and simulation. ...
Dos conceitos fundamentais da termodinâmica ao resetting de computadores quânticos
(Universidade Federal de São Carlos, 2022-04-18)
Thermodynamic has been known and studied for centuries, whereas the field of computing, more specifically quantum computing, is new and currently a lot of research has being done to understand and develop this field of ...
A study of SnO2 nanowire FET devices: ambipolarity effect induced by UV Light exposure and their use as UV sensors
(Universidade Federal de São Carlos, 2021-03-18)
In this work, SnO2 nanowires (NW) were grown by the Vapor-Liquid-Solid (VLS) method and used to build single NW FET devices. As-grown samples went through structural and morphological analysis and seven single NW devices ...
Desenvolvimento de nanoestruturas de TiO2 com superfície modificada pela presença de espécies de Fe e a avaliação da sua performance fotocatalítica
(Universidade Federal de São Carlos, 2022-07-29)
The development of society has increasingly demanded technological evolution in order to supply its needs, resulting in environmental costs that can lead to severe damage. Among these impacts, the pollution of springs and ...
O efeito Zeno no controle da evolução adiabática de um sistema quântico a partir de medidas não-seletivas
(Universidade Federal de São Carlos, 2022-07-26)
The objective of the present work is to improve the performance of a Stimulated Raman Adiabatic Passage (STIRAP) in a 3-level system by applying successive non-selective measurements throughout the evolution (exploiting ...
