Propagation of Higher Order Correlation Beams in Turbulent Atmosphere
(Universidade Federal de Minas GeraisUFMG, 2016-03-02)
This Thesis deals with theoretical aspects of atmospheric propagationof correlation beams. The correlation beam is prepared in the processof low gain spontaneous parametric down-conversion in the two photonregime within ...
Modulador espacial de luz para processos quânticos: algoritmo de Deutsch, concentração de emaranhamento e simulação desistemas quânticos abertos
(Universidade Federal de Minas GeraisUFMG, 2013-04-26)
In this thesis we demonstrate experimentally the implementation of quantum processes and simulation of complex dynamics, through the manipulation of a quantum system. Pairs of entangled photons generated by spontaneous ...
Discussão sobre complementaridade em sistemas quânticos de dois q-dits
(Universidade Federal de Minas GeraisUFMG, 2014-01-24)
In this work, we will deal with pure, bipartite quantum systems of two q-dits (arbitrary dimensions). In these systems, we will study the complementarity between the local entities Predictability and Visibility (that ...
A complementarity-based approach to phase in finite-dimensional quantum systems
(2005)
We develop a comprehensive theory of phase for finite-dimensional quantum systems. The only physical requirement we impose is that phase is complementary to amplitude. To implement this complementarity we use the notion ...
ANÁLISIS DE CORRELACIONES CUÁNTICAS EN SISTEMAS DE MUCHAS PARTÍCULAS Y SUS APLICACIONES EN INFORMACIÓN CUÁNTICA
(Biblioteca Digital wdg.biblioUniversidad de Guadalajara, 2016)
Introducción
La implementación experimental de la mayoría de los protocolos de información cuántica
involucra un considerable número de dispositivos. El monitoreo del sistema, requerido para
la corrección de errores ...
Sharing of D-dimensional quantum states
(2012)
We propose a scheme for the deterministic sharing arbitrary qudit states among three distant parties and characterize the set of ideal quantum channels. We also show that the use of non-ideal quantum channels for quantum ...
Mutually unbiased bases and discrete Wigner functions
(2007)
Mutually unbiased bases and discrete Wigner functions are closely but not uniquely related. Such a connection becomes more interesting when the Hilbert space has a dimension that is a power of a prime N=dn, which describes ...

Operações quânticas em circuitos fotônicos integrados: tomografia de estados e medidas de coerência
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2020-07-09)
This work proposes to carry out a study on integrated photonic circuits. Our goal is to develop a methodology for obtaining the parameters of a photonic circuit that allows us to perform a set of quantum operations necessary ...
Quantum ptychography
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2022-02-18)
Nós propusemos um novo método para reconstruir estados quânticos, chamado pticografia
quântica. Esse método se baseia em uma analogia com a pticografia, um método de
reconstrução de fase na óptica clássica.
A principal ...
