Obtaining such guarantees is often difficult and both time consuming and error-prone. Starting with the work of Drori and Teboulle (2014), novel techniques have been used to gain numerical insights, leading to the release of various performance estimation (PE) software. <br>\r\n<br>\r\nIn this talk, I will show how various computer-aided techniques can be used to study first-order optimization methods in a systematic way. From performance estimation problems with automated Lyapunov discovery, to symbolic regression and computer algebra systems, novel tools completely reshape the way we approach theory of optimization. <br>\r\nAs a main example, I will focus on error feedback methods used with compressed communication in distributed optimization. While error feedback has been widely studied, existing theory often provides untight (thus unreliable) bounds. I will present tight analyses with matching lower bounds that allow a fair comparison between error feedback schemes and standard compressed gradient descent, and help explain when error feedback is useful and when it is not.<br>\r\n<br>\r\nOverall, the talk aims to show how various computer-aided proofs can lead to clearer and more reliable insights into first-order optimization methods.<br>\r\n<br>\r\nBased on :<br>\r\n<a href=\"https://icml.cc/virtual/2026/poster/62713\" target=\"_blank\">A Tight Theory of Error Feedback Algorithms in Distributed Optimization,</a> DB Thomsen, A Taylor, A Dieuleveut<br>\r\nInternational Conference on Machine Learning (ICML 2026)<br>\r\n<a href=\"https://scholar.google.com/citations?view_op=view_citation&hl=fr&user=ge-OinUAAAAJ&sortby=pubdate&citation_for_view=ge-OinUAAAAJ:q3oQSFYPqjQC\" target=\"_blank\">Tight analyses of first-order methods with error feedback</a>, DB Thomsen, A Taylor, A Dieuleveut<br>\r\nAdvances in Neural Information Processing Systems (NeurIPS) (2025).<br>\r\n<a href=\"https://scholar.google.com/citations?view_op=view_citation&hl=fr&user=ge-OinUAAAAJ&sortby=pubdate&citation_for_view=ge-OinUAAAAJ:L8Ckcad2t8MC\" target=\"_blank\">PEPit: computer-assisted worst-case analyses of first-order optimization methods in Python</a><br>\r\nB Goujaud, C Moucer, F Glineur, JM Hendrickx, AB Taylor, A Dieuleveut<br>\r\nMathematical Programming Computation 16 (3), 337-367 (2024)<br>\r\n(eventually - as a detour) <a href=\"https://scholar.google.com/citations?view_op=view_citation&hl=fr&user=ge-OinUAAAAJ&sortby=pubdate&citation_for_view=ge-OinUAAAAJ:wbdj-CoPYUoC\" target=\"_blank\">Provable non-accelerations of the heavy-ball method</a> B Goujaud, A Taylor, A Dieuleveut, Mathematical Programming, 1-59 (2025)<br>\r\n </p>", "image_description": "", "creation_date": "2026-05-19T09:20:45", "last_modification_date": "2026-05-19T09:22:37", "link_label": "", "link_url": "https://www.epfl.ch/schools/sb/research/math/research/statistics/", "canceled": "False", "cancel_reason": "", "place_and_room": "CM 1 517", "url_place_and_room": "https://plan.epfl.ch/?room==CM%201%20517", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "Aymeric Dieuleveut, Ecole Polytechnique, Institut Polytechnique de Paris", "organizer": "Myrto Limnios ", "contact": "Maroussia Schaffner", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 3, "fr_label": "Entrée libre", "en_label": "Free" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/120800/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/5/?format=api", "https://memento.epfl.ch/api/v1/mementos/7/?format=api", "https://memento.epfl.ch/api/v1/mementos/288/?format=api" ] }, { "id": 71896, "title": "Cavity quantum electrodynamics with a Fermi gas in a cavity microscope", "slug": "cavity-quantum-electrodynamics-with-a-fermi-gas--2", "event_url": "https://memento.epfl.ch/event/cavity-quantum-electrodynamics-with-a-fermi-gas--2", "visual_url": "https://memento.epfl.ch/image/33214/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/33214/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/33214/max-size.jpg", "lang": "en", "start_date": "2026-05-29", "end_date": "2026-05-29", "start_time": "16:00:00", "end_time": null, "description": "<p>Thesis Director: Prof. J.-Ph.

While most studies have focused on simulation of systems with short-range interactions, their interplay with long-range interactions remains largely unexplored. <br>\r\nIn our experimental platform, the atomic ensemble is strongly coupled to a high finesse optical resonator, whose photons mediate an effective long-range interaction among the particles. Upon reaching a critical long-range interaction strength, the system undergoes a phase transition into a density wave ordered state, characterized by the superradiant build-up of the cavity field and the atomic self-organisation into a crystalline lattice. While this phenomenon has been extensively studied in bosonic quantum gases, we explore the effect of this transition in a degenerate two-component Fermi gas with tunable short-range interactions. <br>\r\n<br>\r\nI will present our recent experimental results, where high-resolution microscopy yields the first real-space observation of the periodic density modulation characterizing the density-wave ordered state. Moreover, the micrometer-scale resolution gives access to high-frequency spatial correlations of the gas in both the density and magnetization observables, and enables precise shaping of the trapping potential - significantly expanding the degree of control over the many-body state. <br>\r\nWe make use of this versatile platform to explore the interplay between the cavity field and the atomic ordering and to investigate how the many-body state of the paired Fermi gas is reshaped by the cavity mediated long-range interactions. <br>\r\n<br>\r\n2. <strong>Quantum Complexity in Many-Body Systems: From Entanglement to Magic</strong><br>\r\nUnderstanding what makes a quantum many-body state complex is a central question in quantum information, quantum computation, and condensed matter physics. Traditionally, entanglement has played a central role in this discussion: it captures genuinely quantum correlations, constrains classical simulability, and provides a powerful diagnostic of phases of matter and out-of-equilibrium dynamics. However, entanglement alone does not fully characterize the computational complexity of quantum states. In particular, highly entangled states can sometimes be efficiently simulated, while universal quantum computation requires an additional resource known as magic, or non-stabilizerness. <br>\r\n <br>\r\nIn this talk, I will give a broad introduction to quantum complexity in many-body systems, focusing on the complementary roles of entanglement and magic. I will explain the physical meaning of magic, its connection to stabilizer states and Clifford circuits, and why it is necessary for quantum computational advantage. I will then discuss how magic can be generated and diagnosed in many-body dynamics, and how it provides new insight into questions such as thermalization, quantum chaos, transport, and classical simulability. <br>\r\n<br>\r\n<br>\r\nBIO:<br>\r\n<strong>Gaia Bolognini</strong> is currently a third year PhD student in the Laboratory for Quantum Gases (LQG) at EPFL under the supervision of professor Jean-Philippe Brantut. Her research focuses on atomic interacting matter, quantum gases and cavity quantum electrodynamics. She obtained her Master's degree at EPFL, where she focused on the assembly and the design of a new technology for quantum gas experiments, the 'cavity-microscope'. She obtained her Bachelor's degree at University of Milano-Bicocca, in my hometown. <br>\r\n<br>\r\n<strong>Emanuele Tirrito</strong> obtained his Master’s degree in Physics from the University of Pisa, working on relaxation and prethermalization in one-dimensional quantum systems. He then completed his PhD at ICFO in Barcelona, where he studied topological phases of matter and developed tensor-network methods for strongly correlated systems. After postdoctoral positions at SISSA, the University of Trento, and ICTP, his research has progressively moved toward quantum information aspects of many-body physics, with a particular focus on entanglement, non-stabilizerness or “magic”, measurement-induced transitions, and quantum simulation. He is currently an SNSF Postdoctoral Fellow at EPFL. <br>\r\n </p>", "image_description": "", "creation_date": "2026-05-22T09:33:34", "last_modification_date": "2026-05-26T17:04:05", "link_label": "", "link_url": "", "canceled": "False", "cancel_reason": "", "place_and_room": "CM 0 13", "url_place_and_room": "https://plan.epfl.ch/?room==CM%200%2013", "url_online_room": "", "spoken_languages": [ "https://memento.epfl.ch/api/v1/spoken_languages/2/?format=api" ], "speaker": "<strong>Gaia Bolognini</strong> <br>\r\n<br>\r\n<strong>Emanuele Tirrito</strong> ", "organizer": "QSE Center", "contact": "[email protected]", "is_internal": "False", "theme": "", "vulgarization": { "id": 2, "fr_label": "Public averti", "en_label": "Informed public" }, "registration": { "id": 3, "fr_label": "Entrée libre", "en_label": "Free" }, "keywords": "", "file": null, "icalendar_url": "https://memento.epfl.ch/event/export/120835/", "category": { "id": 1, "code": "CONF", "fr_label": "Conférences - Séminaires", "en_label": "Conferences - Seminars", "activated": true }, "academic_calendar_category": null, "domains": [], "mementos": [ "https://memento.epfl.ch/api/v1/mementos/5/?format=api", "https://memento.epfl.ch/api/v1/mementos/389/?format=api", "https://memento.epfl.ch/api/v1/mementos/6/?format=api", "https://memento.epfl.ch/api/v1/mementos/8/?format=api", "https://memento.epfl.ch/api/v1/mementos/296/?format=api", "https://memento.epfl.ch/api/v1/mementos/27/?format=api", "https://memento.epfl.ch/api/v1/mementos/191/?format=api" ] }, { "id": 70771, "title": "Training \"Reshaping Information Research with AI\"", "slug": "training-reshaping-information-research-with-ai-9", "event_url": "https://memento.epfl.ch/event/training-reshaping-information-research-with-ai-9", "visual_url": "https://memento.epfl.ch/image/32182/200x112.jpg", "visual_large_url": "https://memento.epfl.ch/image/32182/720x405.jpg", "visual_maxsize_url": "https://memento.epfl.ch/image/32182/max-size.jpg", "lang": "en", "start_date": "2026-06-02", "end_date": "2026-06-02", "start_time": "10:00:00", "end_time": "12:00:00", "description": "<strong>In the last few years, many AI-powered tools promise to change forever the way we look for information.
