The idea is to decouple the journals from the review step. They’ll still exist, but they’ll need to add other value. They’ll highlight, curate, add new perspectives. If they do a good job they can still be prestigious (like Scientific American or Wired) (1.2) 👇

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

Last week, we published a paper that really excites me:
"Circuit compression for 2D quantum dynamics"

Using Pauli propagation, we (Matteo) were able to compress Trotter circuits for systems up to 30x30 with depth reductions of x2 to x13.

Uploaded (replaced) a paper to arXiv today for the first time in a while.. and discovered some new features! 🤩

✅ You can choose your compiler (incl. pdflatex)
✅ You can select the top-level TeX file
✅ There is a new "Review Files" stages that detects which files are unused!

🥰 and more: ... 1/3

🚨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 !
Characterizing quantum resourcefulness via group-Fourier decompositions
In this work we present a general framework for studying the resourcefulness in pure states for quantum resource theories (QRTs) whose free operations arise from the unitary representation of a group....

Seeing our software and resources be used by other researchers and practitioners in the qc space gives me extreme "academic pride", for a lack of better words 🥲

Here's to more well-documented code in 2025

To 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. See our conclusions here arxiv.org/abs/2501.05694

Hey #Quantumsky 👋🏾

This is an attempt at indexing the growing quantum community here on Bluesky. Please let me know if you'd like to be added to the list.

Genuinely happy to see what looks like a successful migration from the birdsite 😄

I open my Bluesky feed and it is full of really cool people saying really smart things and being really passionate about really interesting stuff.

I like this version of social media, and the world.

After an admittedly failed first attempt for me personally, it somehow feels quite nice to be part of this (still small, mildly active) bubble, this time around. I'm so intrigued to see whether we'll manage to keep things alive as long as we need to, and within bounds after that! 🦋
