Title: "Everything You Always Wanted to Know About Many-Body Dynamics*" Quantum theorists (and even some experimentalists) throw around words like many-body localization, quantum chaos, scrambling, OTOCs, time-crystals, scarring, eigenstate thermalization hypothesis, to describe interesting features of many-body time dynamics. But what do these concepts mean, theoretically or phenomenologically, how are they observed, and why are these concepts interesting in the first place? As part of the Quantum Limits <https://qutech.nl/quantumlimits/> project<https://qutech.nl/quantumlimits/>, the goal of this meeting is to foster connections between Delft and Leiden, build a shared language on questions of thermalization, equilibration and chaos, and kick-off future regular discussions exploring research questions that push towards the time quantum limit. *But Were Afraid to Ask Click here to register and see the program <https://docs.google.com/spreadsheets/d/1bkWIMG_8i0rdAV6XuKKhXSfvy-T_JvzetbN…> If you are planning to attend, please register so we can make sure to get enough (yet not too much) snacks and drinks. Hope to see you there! Best, Francisco, Barbara, and Koenraad EXTRA ADDITION: POSTER SESSION Given the large interest and to further stimulate discussions among all participants, we are adding a poster session to the half-day tutorial. This is an opportunity for PhDs and postdocs to present experimental or theoretical work on explorations of many-body dynamics during the borrel at the end of the day. Please align with your PI whether he/she believes presenting a poster is suitable for this event. We have room for 10 posters, please email F.Machado(a)tudelft.nl<mailto:F.Machado@tudelft.nl> with a title, abstract and authorlist of your poster (plus arxiv.org link if available) before Jan. 16 (for the health of my inbox, please use the email subject "Half-day poster"). In case of too many submissions, we will have to, unfortunately, select only 10 poster submissions. Confirmation will be sent to you by Jan. 19. The posters should be setup at 12h30, i.e. 1 hour before the first talk in the hallway near the Mooij zaal. Boards will be provided. Moreover, the talks can also be attended via a Teams link (physical registration is limited to 90 people) through this link<https://teams.microsoft.com/meet/33052871902846?p=J5u1U5pc6a0yrdyn47>. Thank you for your participation and interest, The organizing team (Francisco, Barbara, and Koenraad)

Sharing an invite to today's talk by Tom O'Brien from Google Quantum AI, more information below: Classified as Internal | Intern -----Original Message----- From: Carlo Beenakker <beenakker(a)lorentz.leidenuniv.nl> Sent: Monday, 20 October 2025 21:58 To: institute(a)ilorentz.org Subject: talk by Tom O'Brien on October 21 reminder of tomorrow's talk; Tom will have quite some news to share! Tuesday October 21, at 11.30, Casimir room (Oort 276), Tom O'Brien from Google Quantum AI will tell us about: What defines progress in near-term quantum computing? Recent advances in experimental quantum devices have pushed the boundary of quantum advantage claims beyond sampling tasks[1], a critical step towards all known quantum computing applications. As we progress into early fault-tolerance in the next five years [2], questions of which applications remain feasible for quantum computers, what new algorithms and applications remain to be found, and how can the field best focus its efforts towards quantum benefit, remain open and intriguing. In this talk I will cover recent advances from Quantum AI in this area [1,2,3,4], and detail the areas we think are the most in need of attention from the quantum community.

Anna Dawid talk today: Teaching neural networks how to speak a language of (quantum) phases of matter
by Hefele, N. (Nina) 30 Sep '25

30 Sep '25

Dear all, Anna Dawid is giving LIACS/LION lunch seminar today. When: Tuesday 30 Sep 2025, 12-13.00 Where: BM.1.26 Speaker: Anna Dawid-Lekowska Title: Teaching neural networks how to speak a language of (quantum) phases of matter Abstract: Neural networks NNs have recently become powerful tools fordetecting different collective behaviors of quantum systems (so-called quantumphases of matter), but their black-box character limits their ability toprovide additional physical insight into these behaviors. In physics, phasesare traditionally identified through order parameters—symbolic descriptorsbased on spin correlators if talking about spin models—which describe thedominant characteristics of the phase. I will begin the talk with an accessibleintroduction to these physics concepts. I will then present TetrisCNN, aconvolutional architecture with parallel branches of differentkernels, that not only classifies phases of spin systems from rawmeasurements but also reconstructs their order parameters in symbolic form.Demonstrations include recovering known descriptors in the one-dimensionaltransverse-field Ising model and uncovering more complex ones in thetwo-dimensional Ising gauge theory. I will also show preliminary results formeasurements done on real quantum device. This approach opens the way forcombining interpretable ML with quantum simulators, with potential impact onautomated discovery of exotic phases of matter. You are all welcome to join. All the best, Nina Hefele
