Talk on Thursday Jul 13, 2023 at 12:00 Place: IFISC Seminar Room Title: Harnessing ordered chaotic systems for quantum reservoir computing Speaker: Guillem Llodrà Bisellach, IFISC Abstract: Quantum reservoir computing (QRC) exploits the dynamical properties of quantum systems for machine learning tasks. We show that optimal performance in QRC can be achieved without resorting to disordered systems. Typically, QRC uses dynamical systems with all-to-all topology and random coupling to avoid redundancies. However, our work explores the emergence of a chaotic phase resulting from the competition between coupling and interaction terms in the one-dimensional Bose-Hubbard model with homogeneous coupling. Our results challenge established design principles and suggest simpler and more efficient implementations of QRC. &nbsp; Presential in the seminar room, and Zoom stream at&nbsp; zoom.us/j/98286706234?pwd=bm1JUFVYcTJkaVl1VU55L0FiWDRIUT09 Url event:https://ifisc.uib-csic.es/en/events/seminars/harnessing-ordered-chaotic-systems-for-quantum-res/

Talk on Friday Jul 07, 2023 at 11:00 Place: IFISC Seminar Room Title: Lagrangian transport of floating plastics at local and regional scales using MOHID-Lagrangian Speaker: Sara Cloux, IFISC Abstract: Marine litter has become an increasingly concerning issue in recent years, largely due to the global population growth. Poor management of plastic waste leads to its accumulation in seas and oceans, creating a widespread problem. Once these plastics reach the marine environment, they undergo a prolonged process of degradation, transitioning from a macro state (plastics with a diameter greater than 0.5 cm) to a micro state (less than 0.5 cm in diameter). Microplastics disperse throughout the oceans, entering the marine food chain and ultimately affecting humans. Therefore, it is crucial to address this issue at the macro scale. In this study, we present the validation of a Lagrangian computational model developed to track the movement of macroplastics in seas and oceans. The validation process focuses on a regional scale, specifically the Arousa Estuary, which is renowned for its mussel farming in northwestern Spain. The significance of this research lies in the comparison of model-predicted accumulation results with the actual accumulation data collected from Galician beaches. Furthermore, we investigate various sources of plastic pollution along the Atlantic coast of Spain, including both land-based and maritime origins, as well as those originating from rivers.
