Presentaremos conceptos fundamentales de conectividad estructural y funcional cerebral, analizando su relación en individuos sanos y su evolución a lo largo de la edad. Discutiremos cómo la edad cerebral basada en conectividad puede ofrecer nuevas perspectivas sobre el desarrollo neurobiológico en niños y adolescentes con autismo, revelando trayectorias atípicas de maduración cerebral. Asimismo, exploraremos enfoques recientes de subtipado en el espectro autista basados en patrones de conectividad funcional, identificando subgrupos caracterizados por hiper e hipoconectividad cerebral, y su vínculo con mecanismos neurobiológicos como el desequilibrio entre excitación e inhibición. Finalmente, destacaremos la importancia de la conectividad cerebral como biomarcador potencial para mejorar la comprensión y caracterización del autismo. > > The SPIN Organizers >

In this work, we consider a photonic-native convolutional neural network similar to the one of [2] consisting of passive linear optical circuits and simple adaptative measurements. We then benchmark the performance and resource requirements of our photonic models against their classical counterparts. >> >> [1] Iris Cong, Soonwon Choi, and Mikhail D. Lukin.

Quantum machine learning advantages beyond hardness of evaluation
by Daniel Manzano 23 Apr '25

23 Apr '25

Interesting paper on today’s arxiv. ------------------------------------------------------------------------------ \\ arXiv:2504.15964 Date: Tue, 22 Apr 2025 15:04:46 GMT (290kb,D) Title: Quantum machine learning advantages beyond hardness of evaluation Authors: Riccardo Molteni, Simon C. Marshall, Vedran Dunjko Categories: quant-ph Comments: Abstract in the mailings abridged due to characters limit. Please refer to the paper for the full abstract \\ The most general examples of quantum learning advantages involve data labeled by cryptographic or intrinsically quantum functions, where classical learners are limited by the infeasibility of evaluating the labeling functions using polynomial-sized classical circuits. While broad in scope, such results reveal little about advantages arising from the learning process itself. In cryptographic settings, further insight is possible via random-generatability - the ability to classically generate labeled data - enabling hardness proofs for identification tasks, where the goal is to identify the labeling function from a dataset, even when evaluation is classically intractable. These tasks are particularly relevant in quantum contexts, including Hamiltonian learning and identifying physically meaningful order parameters. However, for quantum functions, random-generatability is conjectured not to hold, leaving no known identification advantages in genuinely quantum regimes. In this work, we give the first proofs of quantum identification learning advantages under standard complexity assumptions. We confirm that quantum-hard functions are not random-generatable unless BQP is contained in the second level of the polynomial hierarchy, ruling out cryptographic-style data generation strategies. We then introduce a new approach: we show that verifiable identification - solving the identification task for valid datasets while rejecting invalid ones - is classically hard for quantum labeling functions unless BQP is in the polynomial hierarchy. Finally, we show that, for a broad class of tasks, solving the identification problem implies verifiable identification in the polynomial hierarchy. This yields our main result: a natural class of quantum identification tasks solvable by quantum learners but hard for classical learners unless BQP is in the polynomial hierarchy. \\ ( https://urldefense.com/v3/__https://arxiv.org/abs/2504.15964__;!!D9dNQwwGXt… , 290kb) ——————————————————————————————————————— --------------------------------------------------------------------------------- Daniel Manzano Quantum Thermodynamics and Quantum Computation Group University of Granada Facultad de Ciencias, Av.

22 Apr '25

Desde el grupo de Termodinámica y Computación Cuántica de la UGR les invitamos al siguiente coloquio, que forma parte de las actividades conmemorativas del Año Internacional de la Física Cuántica. El coloquio tiene un nivel accesible para estudiantes de grado. Titulo: El principio de incertidumbre: Un viaje a la teoría de las Medidas Cuánticas Ponente: Dr. Michalis Skotiniotis (QTCG) Resumen: La famosa relación de incertidumbre de Heisenberg, planteada hace casi un siglo, marcó un cambio radical en la forma en que abordamos el proceso de medición. Este Q-lloquium explorará el desarrollo del principio de incertidumbre durante el último siglo, desde la formulación original de Heisenberg hasta sus aplicaciones modernas en la teoría de mediciones cuánticas ultraprecisas. Fecha y hora: Viernes 25 de Abril, 12:00 Lugar: Aula F01. Facultad de Ciencias.
