PhD position. PhD position in Quantum Technologies for Theoretical Physics at Institute for Theoretical Physics (IFT) UAM-CSIC https://www.cuantica2025.es/job-market

Sit down & buckle up. Behind this rather innocent title is the paper that caused the most fraught arguments of any of my career. Are these arguments important? Probably not. Am I going to tell you them anyway? Absolutely. Here is the story of a rollercoaster of a paper. 🎢👇

This was a really cool project to work on! Matt is an amazing researcher, go follow him! Also, he's on the job market for a postdoc 😋😉

I am extremely proud of this review article to Quantum Machine Learning 🌟🌟 arxiv.org/abs/2511.15969 Our goal was to give a bird's eye view of QML, from quantum PAC, to Linear Algebraic approaches and variational methods. Huge thanks to my co author Su Yeon Chang@

If you've ever been curious about statistics and random dynamics in general quantum settings, here's some new work on moments of ensembles of random quantum channels, with the amazing @dgarciamartin.bsky.social , @qzoeholmes.bsky.social , and @mvscerezo.bsky.social !! arxiv.org/abs/2511.12700

When you realize the whole yearly budget for Quantum journal is equal to 8 Nature APCs - and they don't even wreck your paper in proof stage because...there is none

The accepted papers for QTML 2025 are listed here: qtml2025.cqt.sg/accepted-pap... #QTML2025

I am so, so happy to see this article published as a perspective in Nature Communications: www.nature.com/articles/s41... More than the paper itself, I thoroughly enjoyed chatting with all my co-authors on the implications of the absence of BPs ~ classical simulability connection

Some statistical features of Haar unitaries can be well approximated in log depth, exponentially faster than previously thought. We give evidence that this is a 'truly quantum' effect by deriving linear lower bounds for orthogonal, Clifford, symplectic, matchgate groups scirate.com/arxiv/2506.2...

📢QSpain convoca el Premio a la Mejor Tesis en Computación Cuántica! 📍 Tesis defendidas en España antes del 30/06/25 🏆 Premios: diploma + presentación invitada en #ICE10 ✈️ Viaje incluido 📅 Presenta tu candidatura hasta el 15/07/25 Más info: shorturl.at/LpO3x

Great conference at Genoa, Italy about "Time in Quantum Theory" (TIQT)😀 I'll use the ocasion to share my related seminar doi.org/10.52843/cas... on our recent paper "Path Integrals from spacetime quantum actions" (doi.org/10.1016/j.ao...). The topic? Unifying "Quantum time" and Feynman's approach

I'm giving an (online) talk next Monday. Be there or be square 🟥 www.thewiser.org/agenda

🚨Excited to share our new paper "Characterizing quantum resourcefulness via group-Fourier decompositions" from last year's LANL Quantum Computing summer School📘 arxiv.org/abs/2506.19696 !

How fast can quantum circuits compile group designs?Recent work arxiv.org/abs/2407.07754 showed that designs over the n-qubit unitary group can be compiled in logarithmic-in-n depth. Can we similarly build short-depth designs over other groups? In our new paper arxiv.org/abs/2506.16005 we answer no.
