Quantum computers herald the arrival of a new era in which previously intractable computational problems will be solved efficiently. However, quantum technology is held down by decoherence, a phenomenon that is omnipresent in the quantum paradigm and that renders quantum information useless when left unchecked. The science of quantum error correction, a discipline that seeks to combine and protect quantum information from the effects of decoherence using structures known as codes, has arisen to meet this challenge. Stabilizer codes, a particular subclass of quantum codes, have enabled fast progress in the field of quantum error correction by allowing parallels to be drawn with the widely studied field of classical error correction. This has resulted in the construction of the quantum counterparts of well-known capacity-approaching classical codes like sparse codes and quantum turbo codes. However, quantum codes obtained in this manner do not entirely evoke the stupendous error correcting abilities of their classical counterparts. This occurs because classical strategies ignore important differences between the quantum and classical paradigms, an issue that needs to be addressed if quantum error correction is to succeed in its battle with decoherence. In this dissertation we study a phenomenon exclusive to the quantum paradigm, known as degeneracy, and its effects on the performance of sparse quantum codes. Furthermore, we also analyze and present methods to improve the performance of a specific family of sparse quantum codes in various different scenarios.
Quantum technologies have shown immeasurable potential to effectively solve several information processing tasks such as prime number factorization, unstructured database search or complex macromolecule simulation. As a result of such capability to solve certain problems that are not classically tractable, quantum machines have the potential revolutionize the modern world via applications such as drug design, process optimization, unbreakable communications or machine learning. However, quantum information is prone to suffer from errors caused by the so-called decoherence, which describes the loss in coherence of quantum states associated to their interactions with the surrounding environment. This decoherence phenomenon is present in every quantum information task, be it transmission, processing or even storage of quantum information. Consequently, the protection of quantum information via quantum error correction codes (QECC) is of paramount importance to construct fully operational quantum computers. Understanding environmental decoherence processes and the way they are modeled is fundamental in order to construct effective error correction methods capable of protecting quantum information. In this thesis, the nature of decoherence is studied and mathematically modelled; and QECCs are designed and optimized so that they exhibit better error correction capabilities.
La tesis «Aclimatación fotosintética, producción y calidad de plantas de vid (Vitis vinifera L.) de la variedad Tempranillo Tinto y Blanco, cultivadas en diferentes escenarios de cambio climático», defendida por Tefide Kizildeniz y dirigida por Juan José Irigoyen y Fermín Morales, ya se puede consultar en acceso abierto.
Atmospheric CO2 concentration has increased from preindustrial level of 280 μmol CO2 mol-1 air (ppm) to currently more than 400 ppm. Intergovernmental Panel on Climate Change foresees that atmospheric CO2 concentration will continue increasing to reach at the end of this century 700 ppm. Due to its greenhouse effect, elevated atmospheric CO2 concentration is leading to higher atmospheric temperatures, a phenomenon that is being accompanied by episodes of less water availability or drought periods. Grapevine (Vitis vinifera L.) is a plant species very sensitive to those environmental factors. Fruit-bearing cuttings of red and white Tempranillo were grown under elevated CO2 (around 700 ppm, versus 400), high temperature (ambient temperature + 4ºC, versus ambient) and water deficit (cyclic drought, versus well irrigated) in temperature gradient greenhouses located at the University of Navarra (Pamplona, Spain) for three consecutive growing seasons (years 2013, 2014 and 2015). Vegetative growth (total vegetative mass and leaf area) was significantly reduced by drought (consistent the three years) and was more associated to a worse substrate water status than to decreases in leaf water content. In spite of decreasing leaf water content in both cultivars, elevated CO2 stimulated more vegetative than reproductive growth. The largest increases of elevated CO2 were observed in leaf and root growth in white and red Tempranillo, respectively. There was a clear interaction between temperature and water availability. Yield was significantly reduced by drought and was year-dependent, being especially low in 2015 due to eventual heat shocks episodes. The high temperatures of the heat shocks (above 35ºC) induced berry burn and browning and finally loss of 50% of the berries. The response of berry quality to climate change-related factors was highly variable and depended on the year. However, some general conclusions can be reached from the three years of experimentation. Thus, the simulated climate change scenarios affected to a greater extent the technological maturity parameters (primary metabolism) than the phenolic maturity (secondary metabolism). In particular, high temperature and drought significantly and consistently increased must pH, due to the decrease in malic acid. On the contrary, elevated CO2 decreased pH associated with significant increases in tartaric acid. These changes of the must affect its quality and potentially that of the resulting wine. Under elevated CO2 concentration, grapevine photosynthesis increases, modulated by temperature and water availability. However, under prolonged exposure to elevated CO2, grapevine down-regulates photosynthesis, decreasing photosynthetic capacity. Grapevine plants underwent photosynthetic acclimation after a long exposure to elevated CO2, regardless of temperature and water availability. Evidence comes from photosynthetic capacity decreases, leaf starch accumulation, and increases in leaf carbon/nitrogen ratio. Photosynthetic acclimation was well correlated to leaf starch, but not to soluble sugars. The white Tempranillo has altered its response to prolonged exposure to elevated CO2. For any given sink size or any given leaf starch accumulation, white Tempranillo always had higher levels of photosynthetic acclimation than the red one. Data suggest that mutation in white Tempranillo has affected loci other than grape color.
“Vivo como si no hubiera mañana porque no lo hay”. Esta frase, de tintes más bien pesimistas, pertenece a Don Draper, el famoso protagonista de la serie televisiva Mad Men. Desde que el programa hiciera su irrupción en la pequeña pantalla en el año 2007, los amantes de la publicidad disponen de un interesante escaparate para viajar al pasado. La historia del talentoso ejecutivo de cuentas y su día a día en la agencia neoyorkina Sterling & Cooper condensa lo mejor y lo peor de la edad dorada de la publicidad: los años sesenta del siglo XX. Aunque se trata de un personaje ficticio, su personalidad hunde raíces en la realidad, la de los hombres de Madison Avenue que hace ya medio siglo se atrevieron a hacer lo imposible: lavar la cara a la vieja industria de la publicidad. Aunque la agencia de Draper se encuentre en la cima del éxito, la serie deja entrever que el “juego” de la publicidad se volvía cada vez más competitivo a medida que la industria se desarrollaba. Es en este entorno cambiante donde las agencias siempre buscan adaptarse para garantizar su supervivencia. Cambiar para sobrevivir o morir en el intento. La “perla de sabiduría” de Don Draper viene a reflejar el sino de las agencias, que históricamente han desarrollado su trabajo en un entorno voluble e incierto. Su comentario deja entrever que las agencias de publicidad, dada la peculiar naturaleza de sus servicios de comunicación comercial, se mueven sobre un terreno extremadamente precario. Con cada avance tecnológico -la irrupción de un nuevo medio de comunicación, por ejemplo- surge la eterna incógnita de si las agencias de publicidad serán capaces de adaptarse al cambio o, por el contrario, tienen sus días contados.
