I'm curious to know if people have encountered papermills in physics, it seems to be a huge problem (great blog btw) forbetterscience.com/2025/11/17/t...

Fun fact: yesterday I gave an outreach talk and when presenting Shor's algorithm I had 24=6×2×2 as an example of prime factoring

This is a fantastic essay and I wonder how much if it directly translates into science (e.g. paper writing as opposed to paper reading these days) danioffline.substack.com/p/everyone-w...

The quant-ph arXiv is on FIRE today 🔥 🔥🔥

A non-physicist friend of mine just today made 10k selling IonQ shares, great times for QC!

Shamelessly stealing this image for every single time I have to explain the Fourier transform in the future

Trying to fit this in my next grant application

Completely abhorred by the correct spelling being "simulatability" and not "simulability".

The most interesting idea I've learnt this week: arxiv.org/abs/2311.10304 In a dissipative setting, if one takes the thermodynamic limit first and then the limit of zero dissipation, you are left with a Liouvillian gap related to the relaxation of the closed system dynamics

One more day, one more chance to pretend that I understand the word "topological"

I am very happy to announce that my first published article „Rapid Thermalization of Dissipative Many-Body Dynamics of Commuting Hamiltonians“ is now published in Communications in Mathematical Physics. rdcu.be/euy1Y I feel honored and humbled to have been accepted in such a prestigious journal.

I have many opinions on scientific writing and one of them is that we should typically aim to do better than "closing a gap" in the literature

A bit overwhelmed by how hard it is to keep track of results I want to learn about

In a new work, we show both numerically and analytically how expectations values of long-range models are robust to imperfections in the underlying Hamiltonian arxiv.org/abs/2506.16451

Is it normal in some areas to cite papers in talks as [senior author] et al.? I saw it done recently and it seems kinda bad

Counting the days down to the point at which we'll have more whitepapers and roadmaps than actual papers

Spotted on the wild (arXiv) this week

New paper today! Very excited to announce we obtain, from first principles, a quantum master equation that both applies in the many-body regime and provably converges to the exact Gibbs state: arxiv.org/abs/2505.20064

The single biggest threat to my and many other's scientific work is Madrid's government attack on public education, today we march against it!

My favourite trait of scientific writing is the shameless overuse of the word "framework"

When public documents appear on national quantum tech etc usually drafted by public servants with a mixed background....who are they asking for advice?

Very excited to show the first paper of my first PhD student! We prove that long-range models have well-behaved partition functions at high temperatures (despite being all-to-all coupled!), and we build sub-exponential time classical algorithms for their approximation: arxiv.org/abs/2504.20901

We are excited to announce the workshop "Entangle This VI" that we are organizing on quantum science and technology in Madrid, 15th-19th September 2025. Registration and abstract submission is currently open! indico.ift.uam-csic.es/event/27/

Hello everyone! I thought I could use my first post here to report on a great meeting that our QuantERA project "TouQan: Towards a useful quantum advantage" has had this week at DAMTP in Cambridge, UK. A full week of stimulating discussions, lots of fun, and quite some progress on the project!

We have created a "Job market" database for quantum related job offers in Spain. Anyone interested in testing it and using it, please let me know. Still in "beta" phase and ironing out the details.

For the last week I really feel like I've really been doing the real Science™ (a.k.a. selling my personal brand to a hiring committee)

I'm happy to see little technical notes like these published in the arXiv arxiv.org/abs/2412.16912

Is there a sense in which classical simulability and Hamiltonian learning should be linked? I often think one as being the inverse of the other (exp values from couplings, vs, couplings from exp values) but this seems naive, and likely proven wrong by

I'd like to continue the old X tradition of doing self-promotion, by talking about a paper of ours that I was particularly happy with www.scipost.org/SciPostPhys....

I never have, and decidedly never will, remember in which base my logarithms are.

Very tempted to use this shift of app as the excuse to start posting properly hot takes
