Fuente de qudits entrelazados utilizando fibra óptica.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Física., 2019)
A lo largo de esta tesis se estudia dos esquemas experimentales fotónicos que generan estados entrelazados. El primer esquema genera un estado entrelazado en polarización de dos qubits con el cual se violó una desigualdad ...
Set of 4d–3 observables to determine any pure qudit state
(Optical Society of America, 2019-05-15)
We present a tomographic method which requires only 4−3 measurement outcomes to reconstruct any pure quantum state of arbitrary dimension . Using the proposed scheme, we have experimentally reconstructed a large number of ...
Controlled generation of mixed spatial qudits with arbitrary degree of purity
(American Physical Society, 2017-09)
We propose a method for preparing mixed quantum states of arbitrary dimension D (D≥2) which are codified in the discretized transverse momentum and position of single photons, once they are sent through an aperture with D ...
Conexão entre teoria de resposta e técnicas de redução de espaço em sistemas físicos com dimensão infinita e controle coerente com estados fótons
(Universidade Federal de Minas GeraisUFMG, 2010-04-30)
In first part this thesis it is developed a general theory aiming a dimension reduced space for molecules under a electromagnetic field effect, resulting at the end in a pathway for an arbitrary system generalization. It ...
Multi-dimensional entanglement generation with multi-core optical fibers.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas.Departamento de Ciencias Físicas.Concepción., 2023)
The common threads of my work in the Ph.D. was entanglement sources and the work and the works that served as an experimental basis are [20, 47]. Here, prove partially entangled state (PES) in quantum information protocols ...
Algebraic Methods for Quantum Codes on Lattices
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas - Sociedad Colombiana de Matemáticas, 2016-07-01)
This is a note from a series of lectures at Encuentro Colombiano de Computación Cuántica, Universidad de los Andes, Bogotá, Colombia, 2015. The purpose is to introduce additive quantum error correcting codes, with emphasis ...
Two qutrits universal quantum gates from the nine-dimensional unitary solutions of the Yang-Baxter equation
(SPIE-INT SOC OPTICAL ENGINEERING, 2007-04-25)
Using the Kauffman-Lomonaco method, some two-qutrits universal quantum gates are derived from the nine-dimensional unitary solutions of the Yang-Baxter equations associated with algebraic structures like the partial transpose ...
Phase retrieval algorithms applied to the reconstruction of photonic quantum states
(Universidade Federal de Minas GeraisUFMG, 2016-08-09)
Reconstructing a wavefront is a problem that appears in many areas of physics and engineering, and leads to many important applications. X-ray crystallography, electron microscopy, femtosecond laser temporal characterization, ...
