Today, my very first paper with my PhD student @QuantNik and our collaborator @gauravmahajn is out on the arXiv: arxiv.org/abs/2604.15269 If you are at QCTiP hosted at @UniofOxford next week, do attend Nikhil's talk about ""Cloning is as Hard as Learning for Stabilizer States""!

Cloning is as Hard as Learning for Stabilizer States

The impossibility of simultaneously cloning non-orthogonal states lies at the foundations of quantum theory. Even when allowing for approximation errors, cloning an arbitrary unknown pure state...

Can quantum cloning be easier than learning for structured classes of states❓ We ask this question for stabilizer states in our recent work: arxiv.org/abs/2604.15269. 1/⚛️

It was a bit nostalgic for me to go back to my mathematical physics roots with this project. Thanks a lot to @BlakajVjosa , Anouar, @danielmalz , and Michael for this fun collaboration, and for teaching me a lot about Gibbs states!

I'm fascinated by desiderata beyond correctness in learning. 🤩 One such property is *privacy*. In our new work scirate.com/arxiv/2510.07193, inspired by Canetti & Karchmer's eprint.iacr.org/2021/764, we plant the seeds for defining and achieving privacy in quantum learning theory! 🌱

Can we reliably learn from untrusted, remote quantum data while keeping our learning strategy and outcomes private? In scirate.com/arxiv/2510.07193, we provide first answers with covert, verifiable quantum learning, extending Canetti–Karchmer ’21 to the quantum setting! 🧵👇

A huge thank you to my coauthors @qubishk , @non0knowledge , and Saachi Mutreja! Their crypto expertise was crucial for the collaboration, and I'm especially grateful that they patiently explained to me all the crypto concepts that I didn't know. 😅🙏

New paper on Hamiltonian learning & testing! Assuming 2-body interactions, we give an optimal Hamiltonian certification procedure as well as (sample-)efficient algorithms for Gibbs learning and certification. For more, please see the excellent thread below by @hippoquantus . 🧵👇

Happy to announce our new paper "Certifying and learning quantum Ising Hamiltonians" scirate.com/arxiv/2509.10239 together with @IMathYou2 , Francisco Escudero Gutiérrez, Aadil Oufkir, and @CambyseRouze. We are focusing on 2-local Hamiltonians (so a bit more general than Ising).

There certainly are more people to thank, but I'll leave it at that for now. Looking forward to an exciting three days here in Berlin!
