We're organising a workshop on "Correlations of quantum many-body systems" in Tuebingen, Germany, from 16th to 20th December: sites.google.com/view/coqmbs/ho… with excellent speakers! Interested in attending? Please, register until 8th Dec. For talks, submit your work until 24th Nov!
I'm looking to hire a postdoc interested in the more Shannon-theoretic aspects of quantum information. Come work with me in Japan! Starting date can be ASAP and should be within the first half of 2025. See bartoszregula.me/recruitment or the official ad at riken.jp/en/careers/res…
New preprint with Bruno Nachtergaele, Simone Warzel, and Amanda Young: "The charge gap is greater than the neutral gap in fractional quantum Hall systems" arxiv.org/abs/2410.11645 We prove that this spectral gap inequality is a general feature of FQH Hamiltonians
Wisdom from physicist Brandon R. Brown about writing about research, shared at this week's @UMDPhysics colloquium. Please, please, read his new book, Sharing Our Science.
What a month for quantum error correction! First the Google result (full error correction with surface code), then MS/Quantinuum (color code computation demo), then AWS (cat qubits + repetition, suppression with scaling), now Yale (GKP beyond breakeven). arxiv.org/abs/2409.15065
New preprint with Angelo Lucia on the critical finite-size gap scaling for frustration-free Hamiltonians on general graphs arxiv.org/abs/2409.09685
Happy to share that my ERC Starting Grant proposal was selected for funding by @ERC_Research! #ERCStG The goal is to mathematically understand the speed of information propagation in quantum many-body models with unbounded interactions, where standard Lieb-Robinson bounds fail
Fünf neue Starting Grants des Europäischen Forschungsrats gehen an die @uni_tue: Juniorprofessor Josef Leibold, Dr. Florian Wimmers, Professor Marius Lemm, Dr. Claire Vernade und Juniorprofessorin Isabel Monte - Herzlichen Glückwusch! 👏 uni-tuebingen.de/universitaet/a… #erc #research
Open postdoc position in mathematical physics in Tübingen! area: quantum many-body theory and related topics duration: 2 years start date: early 2025 deadline: October 31, 2024 More info, including how to apply: math.uni-tuebingen.de/de/forschung/m…
Preprint uploaded. We prove the generalized quantum Stein’s lemma and the 2nd law of resource theories, both static and dynamical. Grateful for the scientific feedback last time and hoping constructive reactions again. Joint work with Masahito Hayashi. arxiv.org/abs/2408.02722
Three world-leading mathematicians, Irit Dinur, Elon Lindenstrauss, and Aaron Naber, have been appointed to the Institute Faculty, bringing unique expertise in pure mathematics and computer science. They will begin their IAS appointments this summer. More: ias.edu/news/three-wor…
This week I’m in Strasbourg for the ICMP 2024, the International Congress in Mathematical Physics organized by @strasbourg_uni !! This is the biggest conference in the math-physics community, taking place every 3 years. It’s so exciting!! @strasbourg #mathphysics #math #physics
Given a random circuit (where each gate is chosen randomly and independently), is there a smaller circuit that implements the same operation? That is, are random circuits compressible? We show that the answer is no, for both random reversible and quantum circuits. Shannon’s 1949…
Great article in Scientific American about the potential of AI in mathematics. scientificamerican.com/article/ai-wil… It is an interview with Terence Tao. We are happy to see Lean cited multiple times, and the recognition of how tools like Lean can revolutionize mathematical reasoning.
