Happy to announce that our paper on how to compute key rates for one-sided device-independent QKD appeared on the arXiv: scirate.com/arxiv/2608.2.... We provide two extensions of the NPA hierarchy that allow to compute key rates in a QKD scenario with one characterized and one uncharacterized party.

I am happy to announce that our newest work on non-local quantum computation (NLQC) has made it to the arXiv: scirate.com/arxiv/2606.2.... For me personally, the main motivation to study these tasks comes from quantum position verification, but it has links to diverse areas such as quantum gravity.

Device independent quantum key distribution with robust self-tests
Device-independent quantum key distribution (DIQKD) provides a model of quantum key distribution with minimal assumptions and highly abstract theoretical building blocks. Although DIQKD frees us from ...

Inclusion constants for free spectrahedra with applications to quantum incompatibility
Building on the matrix cube problem, inclusions of free spectrahedra have been used successfully to obtain relaxations of hard spectrahedral inclusion problems. The quality of such a relaxation is qua...

Happy to announce our new paper "Certifying and learning quantum Ising Hamiltonians" scirate.com/arxiv/2509.1..., together with Matthias C. Caro, Francisco Escudero Gutiérrez, Aadil Oufkir, and Cambyse Rouzé. We are focusing in this paper on 2-local Hamiltonians (so a bit more general than Ising).

New day, new paper, this time on Heisenberg-limited Hamiltonian learning for continuous variable systems with engineered dissipation: scirate.com/arxiv/2506.0.... The idea is to use strong dissipation to restrict the Hamiltonian evolution onto a convenient subspace where we can learn it.

We have a new preprint out on the topic of quantum position verification and non-local quantum computation (NLQC): scirate.com/arxiv/2505.2.... We are comparing different NLQC tasks and find reductions between them (in the sense of if I can do task 1, then I can do task 2 with an extra EPR pair).

If you are interested in quantum non-classicality, you might enjoy our new preprint: scirate.com/arxiv/2504.1.... In it, we use the framework of general probabilistic theories to connect different forms of non-classicality, in particular measurement incompatibility, steering, and Bell non-locality.
