News!

Finally out on the arXiv, the result of my summer internship at IBM, where I had the occasion to work with 45 and even 58 qubits circuits for molecular simulation! We extend the sample-base quantum diagonalization to excited states, and it shows best-in-class performance!

About me

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"


I'm a Ph.D. student 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.
