⚠️New paper out from our Quantum Computing Summer School! We introduce Quantum Gaussian Processes, QGPs, a Bayesian framework for learning directly from quantum data. arxiv.org/abs/2605.00099 see 🧵

Today, as part of our Strategy on Quantum Technoolgies, @csic.es announced the creation of a new research institute in Madrid, the Quantum Advanced Research Center or QuARC @quarc-csic.bsky.social This new institute launches now with 24 PIs and a total of 100 researchers 1/ quarc.csic.es

Four QUICK sloths (🦥) from @jku.at in Hogwarts, aehm Oxford: Mario, Marwa, @dgarciamartin.bsky.social and yours truly. QCTiP 2026 (qctipconf.github.io) has been a blast. This was my first time as a PC chair and I am happy+proud how everything turned out. Huge thanks to everyone who contributed!

Extremely proud to see our paper "Quantum Convolutional Neural Networks are Effectively Classically Simulable" published in PRX Quantum journals.aps.org/prxquantum/a... This is an instantiation of our work, provable absence of barren plateaus implies classical simulability.

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@

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...

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.
