New paper out on PRA! Together with Antonio Zelaquett Khoury and his experimental team at UFF, we apply quantum information tools to witness dimension and coherence in classical fractional orbital angular momentum states of a laser beam. journals.aps.org/pra/abstract...
McDoing is a great term to describe the modern trivialization of existentialism as consumable performance.
Anguish is content, commitment is a vibe.
The University of Cambridge is hosting a Foundations of Quantum Technologies conference on September 15–18th to mark the 100-year anniversary of the discovery of modern quantum mechanics.
Abstract submissions for talks and posters close May 4th.

New preprint out! It's on interaction-free detection of multiple objects using a single photon, using @quandela.bsky.social 's cloud-based photonic quantum computers. This is the outcome of Sara's Master's dissertation, done in collaboration with Anita Camillini (CINECA). scirate.com/arxiv/2604.0...
LLMs and agents are much more capable now than they were just a year ago - if you're a researcher, I recommend watching this. They're great for coding, and good for brainstorming ideas, criticising text, digging up related published work, and even helping with proofs (with care and caveats).
Not so marvelous news.
~95,000 scientists have left the federal government since the Trump regime took over.

A growing group of companies is advancing photonic quantum computing, using light-based qubits for scalable, room-temperature systems. Firms like PsiQuantum and Xanadu are leading efforts across silicon photonics and optical architectures.

Charles Bennett and Gilles Brassard have been named the winners of the A.M. Turing Award, one of the highest honors in computing, for their work establishing the foundations of quantum information theory. The award comes with a $1 million prize. www.quantamagazine.org/quantum-cryp...
A very good article on AI and coding from the NYT

If you shuffle a deck of cards and then hide most of the labels on the cards, no-one will know what permutations you made. But in the #quantum world, this intuition fails in surprising ways, hinting at deep links between information, symmetry and computation. 🧪⚛️ physicsworld.com/a/physicists...
In Natal, Brazil for the "Quantum at the Dunes" Workshop, it's been great!
In case you're interested, CSIC is still looking for experimentalists on quantum technologies. Just keep an eye on these and other calls, or talk to us for possible future openings.

“Individual ICE agents get money per head that they detain – the guards told me that,” [...] "administration ordered ICE officials to detain more people, [...]. Reports immediately began to emerge of international travellers being detained by ICE officers." It does not feel very safe.
Dr. Walborn and I spoke about QRNG use cases, self-testing and certification, the underlying mechanism for guaranteeing randomness, API versus on-premises options, and Sequre Quantum’s plans for integrating its QRNG into its own PQC and/or QKD solutions.

I’ve been very lucky to learn so many things together with them along their PhD journeys. Looking forward to following the next steps in their careers! 6/n, n=6.
@sara-franco.bsky.social is a 2nd-year PhD student working on scaling up photonic quantum computers - currently we’re looking at ideas to explore together with quantum computing company quandela.bsky.social, where she’ll be an intern later this year. 5/n www.linkedin.com/in/sara-fran...
Mafalda Ramôa works on optimizing variational quantum algorithms, in particular for quantum chemistry. Check out her many publications with co-supervisors Luís Paulo Santos (Univ. Minho) and Sofia Economou from Virginia Tech, where Mafalda is currently based: 3/n

Alexandra Ramôa works on Bayesian methods for quantum amplitude estimation, device calibration, and planning. She’s done internships with groups in Tokyo (Akihito Soeda), Texas (Scott Aaronson), and Valencia (Germán Rodrigo) – Lucky them! 4/n sites.google.com/view/alexand...
Anita Camillini is already writing up her thesis, and she currently works in the quantum computing group of Cineca (Italian HPC). Her work spans linear-optical protocols for device certification and indistinguishability distillation, among other topics. 2/n www.hpc.cineca.it/staff/camill...
Feb. 11th was the International Day of Women and Girls in Science - let me briefly highlight here the 4 brilliant female PhD students I currently supervise, hosted at @inlnano.bsky.social : Anita Camillini, Alexandra Ramôa, Mafalda Ramôa, and Sara Franco. A thread 1/n

The world's first quantum satellite crashed into the Pacific last week (to the west of Ecuador) after an almost 10-year mission
Also known as Mozi (& QUESS) it was famously the first to teleport a photon to space (or at least its quantum state)

We take randomness for granted.
Early PRNGs were BAD.
Thousands of scientific papers used to rely on RANDU, created by IBM in the 1960s.
In 1D space, it looks ok!
Map in 3D…you start to see the issues. Now, there *was* a better solution...but it would cost you.
Just wrapped up my minicourse on photonic quantum computation, as part of the XVIII Jorge André Swieca Optics Summer School, held at UFF. Here are some notes notes and slides: sites.google.com/id.uff.br/sw...
New preprint out! Jointly with Marco Robbio and Leonardo Novo (INL), and Nicolas Cerf (ULB). We show how to efficiently measure multivariate traces of quantum states (AKA Bargmann invariants) using linear optics, with multiple applications. scirate.com/arxiv/2601.1...

“Uruguay did what most nations still call impossible: it built a power grid that runs almost entirely on renewables—at half the cost of fossil fuels. The physicist who led that transformation says the same playbook could work anywhere—if governments have the courage to change the rules.”
Imagine if the US attempted to learn from Uruguay instead of invading Venezuela
