Zoltán Zimborás @zoltanzimboras.bsky.social · 01/10/2026In our new preprint (prepared in the current QIP rush), we ask: How hard is it to simulate free fermion dynamics with magic input states classically? The reply is condensed in the Table below. Paper: scirate.com/arxiv/2609.4... arxiv.org/abs/2609.40187 1/6 180
Zoltán Zimborás @zoltanzimboras.bsky.social · 13/03/2026This week scalable quantum generative learning finally reached bosonic systems: scirate.com/arxiv/2603.1... 1/3 140
Zoltán Zimborás @zoltanzimboras.bsky.social · 09/01/2026Great thread by Stefan Knecht on the new paper by the Garnet Chan group: "FeMoCo hasn’t been entirely solved, but for its gold-standard active space model (which is the model QC folks have been looking at!), there is now a classical benchmark that provides an excellent baseline for any quantum work" 071
Zoltán Zimborás @zoltanzimboras.bsky.social · 26/11/2025A larger update of our Majorana propagation paper is out! arxiv.org/abs/2503.18939 050
Zoltán Zimborás @zoltanzimboras.bsky.social · 19/11/2025Happy to see that our paper on the classical training and quantum inference of Fermionic Born Machines is now out on arXiv! 1/6 scirate.com/arxiv/2511.1... 1120
Zoltán Zimborás @zoltanzimboras.bsky.social · 08/11/2025Super happy to see that our paper on the "Quantum generalizations of Glauber and Metropolis dynamics" with Anthony Chen, Csaba Czabán, João Doriguello, András Gilyén, Balázs Kabella, Michael Kastoryano, József Mák was accepted as a talk at #QIP2026 🎉🎉🎉 0100
Zoltán Zimborás @zoltanzimboras.bsky.social · 30/08/2025Thanks a lot for visiting, Alex (@physicistalex.bsky.social)! It was super nice and productive - we found a couple of nice platonic ideas concerning hyperbolic tilings and spin models. 160
Zoltán Zimborás @zoltanzimboras.bsky.social · 01/07/2025The paper was a result of a wonderful collaboration with Lorenzo Grevink, @haferjonas.bsky.social , @markusheinrich.bsky.social, Jonas Helsen, Marcel Hinsche, Tommy Schuster that started during a discussion at the Random Quantum Circuits in Amsterdam. 160
Zoltán Zimborás @zoltanzimboras.bsky.social · 01/07/2025In our new paper, we derive linear lower bounds on the circuit depth of Clifford, orthogonal, symplectic, matchgate designs (built of local gates from the respective groups). 090

Zoltán Zimborás @zoltanzimboras.bsky.social · 11/06/2025ArXiv seems broken this morning, can't get the pdf of today's papers. (Btw, the html option still works, so one can access the papers in that form.) @arxiv-quant-ph.bsky.social 050
Zoltán Zimborás @zoltanzimboras.bsky.social · 25/03/2025Our new Majorana Propagation method is out! It can be used either alone as a classical simulation method or in conjunction with quantum subroutines, see @qzoeholmes.bsky.social's thread below. (Btw, it's so efficient that it broke scirate: this and all papers after ours are missing from scirate.) 0151
Zoltán Zimborás @zoltanzimboras.bsky.social · 21/02/2025Happy to share that I will join University of Helsinki as a Professor at the Department of Physics. The team at UH has been incredibly welcoming, and I’m looking forward to working here. More to come soon (e.g., announcements of open postdoc, PhD positions)! 6390
Zoltán Zimborás @zoltanzimboras.bsky.social · 11/02/2025Wow! Wonder how what Google map shows in Mexico.... 130
Zoltán Zimborás @zoltanzimboras.bsky.social · 09/02/2025Recently, I was rereading Carl Sagan’s book, "The Demon-Haunted World: Science as a Candle in the Dark" published in 1995. I am just now randomly posting a paragraph from it; you know, any resemblance to actual events is purely coincidental. 1112

Zoltán Zimborás @zoltanzimboras.bsky.social · 13/01/2025To reach some consensus about the prospects of near-term (late nisq and early fault tolerant) quantum computing, we had a 3-day discussion event (“Quantum Now”) in Lapland with both optimists and pessimists. This continued at SeeQA 2024 in Oxford.
