SUMMARY:On the Asymptotic Global Structure of Duality Frames in Quantum Gravity
DESCRIPTION:Speaker: Ignacio Ruiz García\n\n\nInstitution: IFT UAM/CSIC\n\n\nLocation&Place: Blue Room\n\n\nAbstract:\n\n\nThis thesis studies the global asymptotic structure of moduli spaces in effective field theories compatible with Quantum Gravity\, focusing on the Swampland Distance Conjecture. We develop taxonomy rules that determine the arrangement of towers of light states and duality frames at infinite distance\, showing a finite set of possible global structures. These towers\, interpreted as emergent degrees of freedom\, are linked to the lowering of the EFT cut-off scale\, leading to a universal relation between the leading tower and the cut-off depending only on spacetime dimension. We test these patterns in string and M-theory compactifications\, recovering known constructions and suggesting new landscape corners or Swampland constraints. Finally\, we explore generalizations in lower-supersymmetry settings\, including non-Lorentzian decompactifications\, changing fibration structures\, and additional asymptotic scales\, to better understand the consistency rules for EFTs admitting UV completion to Quantum Gravity.\n\nSupervisor: Irene Valenzuela Agüí

SUMMARY:Exploring infinite distance limits of type II Calabi–Yau compactifications
DESCRIPTION:Speaker: Luca Melotti\n\n\n\nInstitution:  IFT UAM/CSIC\n\n\n\nLocation&Place: Blue Room\n\n\n\nAbstract:\n\n\nThis thesis explores infinite distance limits in the vector multiplet moduli space of type II string theory on Calabi–Yau threefolds. First we classify such limits\, identify the towers of light states\, and test the Emergence Proposal\, which links IR kinetic terms to loop corrections from such states. We then study the scalar curvature of the moduli space along infinite distance trajectories\, focusing on cases where it diverges positively. We argue that such divergences signal decoupled field theory sectors and propose this as the only mechanism for curvature divergences in quantum gravity. Extending the analysis\, we relate these limits to higher-dimensional rigid theories (5d/6d SCFTs and Little String Theories)\, interpreting divergences as a parametric separation between the strength of gravitational and gauge interactions. Finally\, we connect curvature divergences with rigid limits and the existence of BPS states with divergent charge-to-mass ratios. \n\nSupervisor: Fernando Marchesano\n

SUMMARY:Design and Implementation of Quantum Algorithms in the Noisy Intermediate Scale Quantum Era
DESCRIPTION:Abstract:\n\n\nQuantum computing is an emerging paradigm that leverages the principles of quantum mechanics to perform calculations potentially more efficiently than classical computing. It is currently at a crucial stage of its development. Despite its rapid advancement and adoption in both academia and industry\, there are still significant theoretical and practical challenges that must be overcome before quantum computing can materialize on a large scale. An essential step on this path is the identification of problems that are intractable for classical algorithms\, but can be efficiently solved by a quantum computer\, thus demonstrating quantum advantage. Although there are various technologies for the implementation of quantum computers\, all are affected to a greater or lesser extent by the presence of errors in the qubits. Therefore\, it is common to perform a classical post-processing of the results to mitigate these errors. This thesis focuses on the development of quantum algorithms to address problems in fields as varied as Condensed Matter Physics\, Game Theory\, and Quantum Machine Learning. In addition\, advanced error mitigation techniques are presented that allow their implementation on current quantum devices. \nSupervisors: Esperanza López\, Germán Sierra.
