- Follow up of longlived dropletsize stability in O/W nanoemulsions for antibacterial applications and their thermoresponsive behaviour(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2025-05-09) Erick Jair, Sánchez Gaitán; Delgado Cepeda, Francisco Javier; emipsanchez; Bandala Solano, Yamir; Dulce Viridiana Melo Máximo; Rosales Hoz, María de Jesús; School of Engineering and Sciences; Campus Estado de México; González López, VianneyAntibiotic resistance is now one of the most worrying global health threats, where common antibiotics have become obsolete. To counteract this urgent crisis, many studies and strategies have been employed to provide an effective solution. Novel therapeutic strategies have emerged, such as nanoemulsions, which offer an alternative to inhibit resistant bacteria. The application of nanoemulsions, specifically those involving essential oils, has the potential to become a constant in the industry due to their properties and capability to inhibit bacteria. Their thermoresponsive properties can make them suitable candidates to treat infections caused by resistant bacteria. This study, conducted as part of the Master of Science degree program in Nanotechnology, aims to analyze the long-lived stability of NEs and their antimicrobial properties as a possible alternative for treating microorganisms that exhibit antibiotic resistance. Hysteresis and thermoresponsive characterization of the NEs is a relevant aspect to ensure the stability of the NEs at possible operational conditions and thus the preservation of the antimicrobial properties of the NE. Finally, computational models will be employed as an approach to understand droplet formation and behavior.
- Topological quantum computing: comprehensive overview and theoretical foundations(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2025-05) Pabón Barbery, Mateo; Delgado Cepeda, Francisco Javier; emipsanchez; Fernández Cabrera, David José; Gutiérrez Vega, Julio César; Jaimes Nájera, Alfonso Isaac; Enríquez Flores, Marco Benjamín; School of Engineering and Sciences; Campus MonterreyThe apparent computational power of Quantum computers suggests a significant speed- up in calculations by leveraging the principles of superposition and entanglement, proper of Quantum Mechanics. However, the quantum information stored is very fragile to thermal excitations (also referred to as noise) and accuracy errors when information is processed via quantum logical gates. Many research areas develop techniques to correct and mitigate such errors; however, progress on the scalability and efficiency of quantum chips is slow. On the other hand, a relatively new technology has been proposed, directly targeting the prob- lem of decoherence by an inherently fault-tolerant quantum processor, Topological quantum Computing (TQC). In this overview, we trace State of the Art, the fundamental concepts, and the theoretical framework to understand systematically the physical consequence of its constituent qubits, non-Abelian anyons, and how to perform computation. The notion of topologically ordered states is built from a toy model, the Toric code, to a physical system exhibiting topological states, the Quantum Hall Effect (QHE). Once topological order is de- rived, the connection of non-Abelian anyons as qubits is bridged by a qualitative explanation, and the comprehension of the fundamental pillars of TQC flows more naturally. Concepts are reviewed under a comprehensive perspective, using clear language, without repetitive expla- nations found in other sources, and at a technisism level readable for a profile with a strong basic Quantum Mechanics background. Finally, a temporal sequence of the most cited and important achievements on topologically ordered systems and states with the perspective on building the first topological quantum computer closes this document, offering a wide picture of today’s state of the art on Topological Quantum Computing.
- Quantum effects in the efficiency of Fenna-Matthews-Olson light-harvesting complexes(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12) González Soria, Bruno; Delgado Cepeda, Francisco Javier; tolmquevedo; Enríquez Flores, Marco Benjamín; Hernández Cárdenas, Gilberto; Carbajal Tinoco, Mauricio Demetrio; Escuela de Ingeniería y Ciencia; Campus Estado de MéxicoRenewable energy continues to be the fastest growing industry among the power sector, the same is true for the development of quantum computing for data analysis. There is a stretch relationship between these two branches of research being brought together by yet another branch of science: biology. Biological light-harvesting complexes (LHCs) involved in the photosynthetic process present energy transfer efficiencies of almost 100\%, providing a source of inspiration for the development new technologies that could mimic these characteristics. One of the most extensively studied LHCs is the Fenna-Matthews-Olson (FMO) complex. This work is focused on the development of a comprehensible model of excitation energy transfer dynamics in the FMO light-harvesting complex. Considering the research branches involved in this study and the different perspectives from which this complex has been analysed, this work will be taking into account some biological considerations at the molecular, genetic and organism levels to avoid unsubstantiated assumptions. The presence of quantum coherence between electronic states of the bacteriochlorophylls concealed inside the FMO complex during the photosynthetic process of green sulfur bacteria has inspired researchers to attempt computer simulations to understand its complexity. Although several methods have been explored to model this quantum phenomenon in the domains of open quantum systems, the traditional methods used do not take into account the memory effects of the surroundings, which is commonly approximated as a phonon bath on thermal equilibrium. A popular solution to overcome this limitation is the application of the hierarchical equations of motion (HEOM) method, a non-Markovian approach also used to analyze the dynamics of such a complex, for the modeling of the system evolution. The proposed variation of the parameters that govern the HEOM method in this study provides a new form of characterization for the FMO system. A parametric analysis of some physical features involved during the excitation energy transfer process is performed to better understand its non-trivial dependence on operation parameters in the quantum realm. The analysis is conducted in terms of the parameters of temperature, relocation energy, and dephasing rate in the system to track the complex global behavior of coherence, entanglement, decoherence times, transference times, and efficiency of the main process of energy transfer. Complementarily, a comparison between two different species is made as a suggestive possible road map to track genetic differences in the photosynthetic performance of the complex through its biological nature.
- Causal order assistance for the quantum teleportation algorithm(Instituto Tecnológico y de Estudios Superiores de Monterrey) Cardoso Isidoro, Carlos; Delgado Cepeda, Francisco Javier; Enríquez Flores, Marco Benjamín; Jaimes Nájera, Alfonso; Procopio Peña, Lorenzo Manuel; Escuela de Ingeniería y Ciencias; Campus Estado de MéxicoDebido a los avances que ha tenido la teletransportación cuántica y a la reciente consideración del orden causal indefinido mostrando mejoras en la comunicación cuántica con canales imperfectos, en este trabajo se abordan las implicaciones en el proceso de teleportación cuando es asistido por un orden causal indefinido, con el fin de corregir que, durante el proceso de teleportación, se utilice un recurso entrelazado muy ruidoso. Al aumentar el número de procesos de teletransportación durante el análisis, surgen alternativas paralelas adicionales para explotar los resultados más valiosos mediante el uso de mediciones débiles como recurso complementario. Finalmente, se presenta una propuesta de una implementación experimental.
