Logic-in-memory circuits promise to overcome the von-Neumann bottleneck, which constitutes one of the limiting factors to data throughput and power consumption of electronic devices. In the following we present four-input logic gates based on only two ferroelectric FETs (FeFETs) with hafnium oxide as the ferroelectric material. By utilizing two complementary inputs, a XOR and a XNOR gate are created. The use of only two FeFETs results in a compact and nonvolatile design. This realization, moreover, directly couples the memory and logic function of the FeFET. The feasibility of the proposed structures is revealed by electrical measurements of HKMG FeFET memory arrays manufactured in 28nm technology.

As a historically racialized utterance, nigger has been a contested and despised word since the late 17th Century. Now, in the 21st Century, nigga is still considered one of the most impactful words in the English lexicon. This dissertation provides one situated and contingent analysis of nigga as a moment of excess in the Higher Education classroom. I wed Judith Butler’s theorizing of ex-citable speech via her analyses of J.L. Austin’s influential conceptualizations of speech acts and Louis Althusser’s interpellation to Henry Louis Gates’ theory of Signifyin(g) in order to interrogate the multitudinous articulations and appropriations of nigga as a Signifyin(g) performative. Through my theorizing of nigger-nigga as a Signifyin(g) performative, I interrogate the continuity and discontinuity of use specific to the English Composition and Literature classroom, as well as within multiple Higher Education classrooms and discussions. I interrogate use through the methodology of what I classify as Foucauldian-lite Discourse Analysis, in order to examine nigger and nigga as ex-citable speech. My intention is to interrogate how these utterances inflect and influence constructions of multiply conflicting and complimentary histories, identities, subjectivities and power relationships of professors and students in visible and invisible ways. The Untitled Supplemental Image is a metaphor for my methodology. The image is of my mother’s hands, which a woven throughout the dissertation, symbolically represents my memory of the first time I heard the utterance nigger.

The few studies of Mormon home literature that have been published to date dismiss it as inferior artistry, an embarrassing if necessary step in the progression towards true Mormon literature. These studies are inadequate, however, because they divorce the texts from their context, holding them up to standards that did not exist for their original audience. Jane Tompkins' theory of texts as cultural work provides a more satisfactory way of looking at these narratives. Home literature is thoroughly enmeshed in the cultural discourse of its day. Beneath the surface, these didactic stories about young Mormons finding love with their foreordained mates performed important cultural work by helping Mormons to think about their personal and collective identities, by co-opting mainstream fictional forms and giving them safe expression, and by reconceptualizing marriage in the wake of polygamy's demise. The stories of Susa Young Gates illustrate these functions well. Gates was a prominent youth leader and prolific home author during the 1890s. Her stories extend and enact Mormon cultural discourse of the time and point up the connections between Mormon fiction and mainstream models. The last decade of the nineteenth century marked the beginning of Mormonism's transition from an isolated separatist movement to a thoroughly assimilated and modem mainstream religion. As Mormons shifted away from the defining practices of polygamy, communal economics, and ecclesiastical dominance of politics, they sought for new ways to define themselves that would retain their sense of distinctness from a world they still viewed as sinful. The result was new emphasis on formerly dormant or relatively unemphasized practices such as the Word of Wisdom and the law of tithing. This emphasis shows up in the story "Donald's Boy" which repeatedly focuses on the necessity for Mormon youth to shun the corruptions of the world. "Seven Times," which ran in the 1893-94 volume of the Young Woman's Journal, shows Gates's debt to mainstream fiction in its extensive adoption of popular conventions, reworking such devices as the heroine's development, the divine child, the lecherous villain, and the sick bed ordeal into a Mormon conversion narrative. As in popular American fiction, the role of the narrator is central to the didactic intentions of the story. The narrator becomes the dominant personality of the text as she both creates and controls the emotion necessary to the formal and ideological demands of the narrative. Gates claimed to consider popular didactic fiction inconsequential, but her own comments and her wholesale use of its conventions suggests that her relationship with these novels was much more complex than she acknowledged. "John Stevens' Courtship" is Gates's most popular and ambitious work. Its setting in the early years of Mormon settlement in Utah at the time of the first large-scale influx of "outsiders" into Mormon society constructs an idealized view of early Mormon culture that contrasts with the diminished faithfulness Gates perceived in her day. Gates's artistic ambitions show up most clearly in her intense descriptions of her characters. These character descriptions draw on popular conventions to inscribe idealized gender constructs that interacted with Mormon ideology to remain in force in Mormon society long after they had faded elsewhere. Finally, Gates's emphasis on the idea of a foreordained mate replaces polygamy as the essential doctrine of marriage, an important shift in post-Manifesto Mormondom.

Quantum information technologies include secure quantum communications and ultra precise quantum sensing that are significantly more efficient than their classical counterparts. To enable such technologies, we need a scalable quantum platform in which qubits are con trollable. Color centers provide controllable optically-active spin qubits within the coherence time limit. Moreover, the nearby nuclear spins have long coherence times suitable for quantum memories. In this thesis, I present a theoretical understanding of and control protocols for various color centers. Using group theory, I explore the wave functions and laser pumping-induced dynamics of VSi color centers in silicon carbide. I also provide dynamical decoupling-based high-fidelity control of nuclear spins around the color center. I also present a control technique that combines holonomic control and dynamically corrected control to tolerate simultaneous errors from various sources. The work described here includes a theoretical understanding and control techniques of color center spin qubits and nuclear spin quantum memories, as well as a new platform-independent control formalism towards robust qubit control. / Doctor of Philosophy / Quantum information technologies promise to offer efficient computations of certain algorithms and secure communications beyond the reach of their classical counterparts. To achieve such technologies, we must find a suitable quantum platform to manipulate the quantum information units (qubits). Color centers host spin qubits that can enable such technologies. However, it is challenging due to our incomplete understanding of their physical properties and, more importantly, the controllability and scalability of such spin qubits. In this thesis, I present a theoretical understanding of and control protocols for various color centers. By using group theory that describes the symmetry of color centers, I give a phenomenological model of spin qubit dynamics under optical control of VSi color centers in silicon carbide. I also provide an improved technique for controlling nuclear spin qubits with higher precision. Moreover, I propose a new qubit control technique that combines two methods - holonomic control and dynamical corrected control - to provide further robust qubit control in the presence of multiple noise sources. The works in this thesis provide knowledge of color center spin qubits and concrete control methods towards quantum information technologies with color center spin qubits.

Las redes ópticas de paquetes se han convertido en los últimos años en uno de los temas de vanguardia en el campo de las tecnologías de comunicaciones. El procesado de cabeceras es una de las funciones más importantes que se llevan a cabo en nodos intermedios, donde un paquete debe ser encaminado a su destino correspondiente. El uso de tecnología completamente óptica para las funciones de encaminamiento y reconocimiento de cabeceras reduce el retardo de procesado respecto al procesado eléctrico, disminuyendo de ese modo la latencia en el enlace de comunicaciones. Existen diferentes métodos de procesado de datos para implementar el reconocimiento de cabeceras. El objetivo de este trabajo es la propuesta de una nueva arquitectura para el procesado de cabeceras basado en el uso de puertas lógicas completamente ópticas. Estas arquitecturas tienen como elemento clave el interferómetro Mach-Zehnder basado en el amplificador óptico de semiconductor (SOA-MZI), y utilizan el efecto no lineal de modulación cruzada de fase (XPM) en los SOAs para realizar dicha funcionalidad. La estructura SOA-MZI con XPM es una de las alternativas más atractivas debido a las numerosas ventajas que presenta, como por ejemplo los requisitos de baja energía para las señales de entrada, su diseño compacto, una elevada relación de extinción (ER), regeneración de la señal y el bajo nivel de chirp que introducen. Este trabajo se ha centrado en la implementación de la funcionalidad lógica XOR. Mediante esta función se pueden realizar diversas funcionalidades en las redes ópticas. Se proponen dos esquemas para el reconocimiento de cabeceras basados en el uso de la puerta XOR. El primer esquema utiliza puertas en cascada. El segundo esquema presenta una arquitectura muy escalable, y se basa en el uso de un bucle de realimentación implementado a la salida de la puerta. Asimismo, también se presentan algunas aplicaciones del procesado de cabeceras para el encaminamiento de paquetes basadas en el uso d / Martínez Canet, JM. (2006).

Para poder satisfacer la demanda de mayores anchos de banda y los requisitos de los nuevos servicios, se espera que se produzca una evolución de las redes ópticas hacia arquitecturas reconfigurables dinámicamente. Esta evolución subraya la importancia de ofrecer soluciones en la que la escalabilidad y la flexibilidad sean las principales directrices. De acuerdo a estas características, las redes ópticas de conmutación de paquetes (OPS) proporcionan altas capacidades de transmisión, eficiencia en ancho de banda y excelente flexibilidad, además de permitir el procesado de los paquetes directamente en la capa óptica. En este escenario, la solución all-optical label switching (AOLS) resuelve el cuello de botella impuesto por los nodos que realizan el procesado en el dominio eléctrico. A pesar de los progresos en el campo del networking óptico, las redes totalmente ópticas todavía se consideran una solución lejana . Por tanto, es importante desarrollar un escenario de migración factible y gradual desde las actuales redes ópticas basadas en la conmutación de circuitos (OCS). Uno de los objetivos de esta tesis se centra en la propuesta de escenarios de migración basados en redes híbridas que combinan diferentes tecnologías de conmutación. Además, se analiza la arquitectura de una red OPS compuesta de nodos que incorporan nuevas funcionalidades relacionadas con labores de monitorización y esquemas de recuperación. Las redes ópticas permiten mejorar la transparencia de la red, pero a costa de aumentar la complejidad de las tareas de gesión. En este escenario, la monitorización óptica de prestaciones (OPM) surge como una tecnología capaz de facilitar la administración de las redes OPS, en las que cada paquete sigue su propia ruta en la red y sufre un diferente nivel de degradación al llegar a su destino. Aquí reside la importancia de OPM para garantizar los requisitos de calidad de cada paquete. / Vilar Mateo, R. (2010).

In this project a qutrit tripod system is studied to implement quantum gates using non-Abelian geometric phases, allowing for holonomic quantum computation which in turn results in more robust computations. First, a general foundation of the theory is presented. This includes the relevant theory of matrices in Hilbert space, as well as theory of the quantum mechanics used in the report. The method is then described in depth, showing how the pulse area is fixed. Using properties of the Hamiltonian as well as the time-evolution operator of the tripod system the computational subspace can be derived. These findings are combined to show how the computational subspace evolves in time, resulting in the unitary matrix used to form quantum gates. Using educated guesses to find the necessary parameters or utilizing iterative methods to find the parameters are the two main approaches used for constructing the considered gates. Three of the suggested quantum gates are successfully implemented through educated guesses, namely X, T and Z using an angle parametrization of the phase and amplitude of the pulses. The last desired gate is the Hadamard-gate, but the implementation of said gate required numerical approximation. The reasons as to why this is the case, are later discussed.
