This year's Quantum Computing Theory in Practice Conference (QCTiP) is scheduled for 04/20/2026-04/25/2026 in Oxford, UK 🇬🇧: qctipconf.github.io Talk submission deadline is just round the corner: 01/11/2026. Looking forward to many exciting contributions and a great time in Hogwarts🪄, aehm Oxford🎓.

Listening this song while writing my PhD thesis

Happy to share that our paper “Complexity of quantum tomography from genuine non-Gaussian entanglement” has been published in Nature Communications! www.nature.com/articles/s41... Thanks a lot to my great coauthors Xiaobin Zhao, Pengcheng Liao, Ulysse Chabaud, and Quntao Zhuang!

Given a mixed state, one can always write down its purifications. However, the “purification operation” is unphysical, i.e. it cannot be realised via a quantum channel. arxiv.org/pdf/2511.234... 1/

This is a publication I am extremely happy about. It is a bit rebellious, and yet it touches upon an old and important question: How can we learn an unknown continuous quantum state from data? www.nature.com/articles/s41... We prove that quantum state tomography is a lot harder than anticipated.

Nature Physics has published our work! nature.com/articles/s4156… Thanks a lot to my amazing coauthors @antonioannamele.bsky.social , Lennart Bittel, @jenseisert.bsky.social, Vittorio Giovannetti, Ludovico Lami, Lorenzo Leone, @sfeoliviero.bsky.social !

So excited that my coauthors and I have three papers accepted at QIP this year! - Optimising quantum data hiding arxiv.org/abs/2510.03538 - Efficient learning of CV Gaussian unitaries arxiv.org/abs/2510.05531 - Is it Gaussian? Testing CV Gaussian states arxiv.org/pdf/2510.07305

The only thing that could possibly be hotter than Italian twins explaining entanglement in Italian is Italian triplets explaining the GHZ state.

Happy to share our TEDx talk where me and my twin @antonioannamele.bsky.social chat about quantum technologies! (Italian only) youtu.be/yzXUsDUPt8A?...

Honoured to have received the Boeing Quantum Creators Prize at the Chicago Quantum Exchange event today! This prize recognises early-career researchers who advance quantum information in new directions

Okay, last post on *quantum learning theory with CV systems* (for a few months🫣) Today's new work tackles another natural and central question in this rapidly developing field: Given an unknown CV state, how to test whether is it Gaussian or not? arxiv.org/pdf/2510.07305 1/

The saga of *quantum learning theory with CV systems* never ends! And indeed, when you look closely at this field, many natural and promising questions arise. For instance: How to learn CV Gaussian unitaries? arxiv.org/pdf/2510.05531 1/

New work on *quantum data hiding*! If you have a quirk for semidefinite/linear programming as an analytical tool for quantum info, this paper might interest you arxiv.org/pdf/2510.03538 1/

Excited and honored to be selected as a winner of the Boeing Quantum Creators Prize 🥳 This international award recognizes early-career researchers who are advancing quantum information science and engineering in new directions! 🔗 chicagoquantum.org/2025BQCP

So honored to receive the award for new talented physicists from the Italian Physical Society🥳 en.sif.it

My website is now online! 🔗 sites.google.com/sns.it/franc... I’ll try to keep it updated with my research work.

I’d like to advertise two cute technical results of today’s paper that may be of independent interest (I hope): A new decomposition of Gaussian unitaries and new bosonic trace distance bounds (the saga of bosonic trace distance bounds never ends! 😍) arxiv.org/abs/2504.19319 1/

New bosonic paper out! Take the covariance matrix of a pure state and count the number of symplectic eigenvalues that are strictly larger than one: this is a powerful non-Gaussian monotone — the *symplectic rank* arxiv.org/abs/2504.19319 1/

New paper out today on "Q Thermo with CV systems"! What is the maximum energy that you can extract from a quantum state via Gaussian unitaries only? We solve this problem by establishing a simple, cute formula for the *Gaussian ergotropy*. 1/ arxiv.org/abs/2503.21748

New paper out!
 We study one-shot q communication over reasonable non-Markovian lossy Gaussian channels. To do so, we prove error bounds on the convergence rate of the *powerful* Avram-Parter's (and Szego's) theorem, which may be of independent interest in matrix analysis. arxiv.org/abs/2503.13207

Our paper on Computable Entanglement Cost has finally been published in PRL. Take a look! journals.aps.org/prl/abstract... @physicists, when you compute the famous *logarithmic negativity*, you should compute our quantity instead! 1/
