[Mar 2026] Can quantum computers help us validate real lab experiments? In our recent work published in Science, we used quantum simulations to confirm the half-Möbius topology of a recently synthesized molecule.

[Sep 2025] Our work on local high-dimensional fermion mappings to qudits has been published in Physical Review A!
[Feb 2025] Extended sample-based quantum diagonalization (Ext-SQD) has been published in Quantum Science and Technology, have a look at the publication!
[Jun 2024] Our work on variational embedding has received a huge update. Now it features not only a strategy to combine quantum variational circuits with classical methods, but also a more general framework to combine classical methods with different accuracies.
[May 2024] Our work that extends the p-VQD algorithm by introducing adaptive circuits for time evolution has been published on Physical Review Research.
The limitations of computing and processing power are no small matter. Rather, they constitute a decisive question, which must be treated with the utmost respect.
- from "Computer meets Theoretical Physics"
Currently, I am a postdoctoral researcher in quantum computing at the IBM Research Lab in Zürich.
I obtained my Ph.D. in Physics at EPFL, in Lausanne, in the group of Prof. Giuseppe Carleo.
My research focuses on the development of quantum algorithms for the simulation of quantum systems.
I work to make the most of current quantum hardware, combining it with methods inspired by classical machine learning.
