Seminar: State Spaces, Quantum Search, and Chess: The Case of Explicit Spaces.
by Daniel Manzano 03 Dec '25

03 Dec '25

Desde el Grupo de Termodinámica y Computación Cuántica (QTCG) de la Universidad de Granada les invitamos al siguiente seminario. ————————————————————— Date and time: Thursday, December 4th. 12:00. Place: Aula de Física Computacional. Área de Física de la Materia (Planta baja del edificio de Física). Facultad de Ciencias. Title: State Spaces, Quantum Search, and Chess: The Case of Explicit Spaces. Speaker: Prof. Manuel Pegalajar. Departamento de Ciencias de la Computación e Inteligencia Artificial. UGR Abstract: Quantum Artificial Intelligence (QAI) has emerged strongly in recent years as a research area that blends the benefits of the quantum computing paradigm with Artificial Intelligence. In this seminar, we will address a classic AI problem: state space search, using a classical formulation that incorporates quantum computing tools for its resolution. Specifically, we will focus on problems that can be modeled as explicit graphs, such as certain chess puzzles. We will frame the resolution of these puzzles as search problems and use algorithms based on Grover's operator to solve them. ————————————————————— Les recordamos que para estar informados de las actividades de nuestro grupo pueden suscribirse a nuestra lista de correo: https://onsager.ugr.es/mailman3/mailman3/lists/qtcg-info.onsager.ugr.es/ Atentamente, --------------------------------------------------------------------------------- Daniel Manzano Quantum Thermodynamics and Computation Group University of Granada Facultad de Ciencias, Av.

Recordatorio de seminario: Geometric foundations of thermodynamics in the quantum regime

02 Dec '25

Desde el Grupo de Termodinámica y Computación Cuántica (QTCG) de la Universidad de Granada les invitamos al siguiente seminaro. ————————————————————— Date and time: Wednesday, December 3rd. 12:00. Place: Aula de Física Computacional. Área de Física de la Materia (Planta baja del edificio de Física). Facultad de Ciencias. Title: Geometric foundations of thermodynamics in the quantum regime Speaker: Álvaro Tejero, QTCG-UGR. Abstract: In this work, we present a comprehensive geometrical formulation of quantum thermodynamics based on contact geometry and principal fiber bundles. The quantum thermodynamic state space is modeled as a contact manifold, with equilibrium Gibbs states forming a Legendrian submanifold that encodes the fundamental thermodynamic relations. A principal fiber bundle over the manifold of density operators distinguishes the quantum state structure from thermodynamic labels: its fibers represent non-equilibrium configurations, and their unique intersections with the equilibrium submanifold enforce thermodynamic consistency. Quasistatic processes correspond to minimizing geodesics under the Bures-Wasserstein metric, leading to minimal dissipation, while the divergence of geodesic length toward rank-deficient states geometrically derives the third law. Non-equilibrium extensions, formulated through pseudo-Riemannian metrics and connections on the principal bundle, introduce curvature-induced holonomy that quantifies irreversibility in cyclic processes. In this framework, the thermodynamic laws in the quantum regime emerge naturally as geometric consequences. Reference: Á.
