The Strange Physics That Gave Birth to AI | Quanta Magazine Modern thinking machines owe their existence to insights from the physics of complex materials.

You may take associative memory for granted, but it’s what allows you to remember a moment from a specific scent, or a full melody from a few lines of lyrics. Physics helped bring a form of this memory to computers.

How did physicists convince people to have conferences at such pretty locations?Had a great time presenting our latest work (arxiv.org/abs/2409.13019) on a new kind of protected qubit formulation- entanglemon-at the Fault-tolerant #QuantumComputing computing workshop in Les Houches.

There’s been exciting experimental progress in quantum simulator platforms in realising exactly these models.We hope our results serve to motivate the exploration of such many body dynamics in these settings as well as clearly disentangle the role of constraints and quantum coherence.

These signatures include asymptotic subdiffusion with tunable dynamical exponents, a dynamical caging mechanism with connections to interesting kinds of random walks and possibly a new growth conjecture!
All of this is for the classical stochastic dynamics in the presence of these gauge constraints.

Fractional diffusion without disorder in two dimensions We analyse how simple local constraints in two dimensions lead a defect to exhibit robust, non-transient, and tunable, subdiffusion. We uncover a rich dynamical phenomenology realised in ice- and dime...

New paper🚨the last work from my PhD thesis.We find an extremely rich phenomenology for dynamical defects(charges) in emergent gauge theories in 2d.Static effects of such emergence has greatly enriched research-we’ve only started to uncover its dynamical consequence. arxiv.org/abs/2504.00074

Given the recent Dwave announcement and the two follow-up classical simulation papers, i think it’s fair to say that the best use case for quantum computers in their present form is to improve classical computation 😅 which to be fair is quite useful , wonder if any startup has used this pitch 🧐

Exactly! Bell Labs invented the goddamn transistor and discovered the goddamn Cosmic Microwave Background! Now "innovation" means adding a chatbot that tells what sports bets you might like to make based on the brand of toilet paper you buy.

First post on Bluesky with a life update. I defended my PhD thesis in Dec @mpipks.bsky.social and am now a postdoc at the TCM department in Cambridge. Looking forward to this new journey and this new platform!
