Estimación de estados cuánticos puros y transformaciones unitarias a través del error cuadrático medio = Estimation of pure quantum states and unitary transformations through the mean squared error.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2022)
En este trabajo se propone un método para estimar un estado cuántico desconocido con alta precisión mediante la minimización del error cuadrático de las amplitudes de probabilidad complejas entre el estado desconocido y ...
Bell nonlocality and quantum teleportation under noisy channels in high dimensional systems

Quantum measurement learning for medical image classification
(Universidad Nacional de ColombiaBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería de Sistemas y ComputaciónDepartamento de Ingeniería de Sistemas e IndustrialFacultad de IngenieríaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-03)
Deep neural networks are the state-of-the-art for medical image classification. However, these models require large data sets to be trained, and they lack some interpretability on their predictions. In recent years, there ...
Robustez da fase topológica fracionária ao ruído e sua demonstração experimental
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2019-08-14)
In 1984, Berry discovered the Geometric Phase that became a characterization parameter of a quantum system. According to Berry, the geometric phase carries itself the geometric and the topologic properties of the parameter ...
A computational intelligence optimization algorithm based on the behavior of the social-spider
(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 ...
Emaranhamento, medidas quânticas gerais e instrumentos quânticos
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2023-01-30)
In this work, the asymmetry properties of quantum states associated with the Hamiltonian
generator of the dynamics of the magnetic dipole interaction are investigated and their relationships with the production of ...
Photonic entanglement sources: high quality and high-dimensional implementations.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Física., 2020)
Entanglement is a physical phenomenon described by the quantum theory. When the system is
composed by two or more entangled particles, their quantum state must be understood as a whole, not as independent quantum states, ...
