Preparing a quantum state that belongs to the physical sector of the Hilbert space is much harder in Lattice Gauge Theories app. than in quantum chemistry. In this paper, with Giulia Mazzola, Simon Mathis we construct circuits to solve this problem. IBM Research arxiv.org/abs/2105.05870

My course "Advanced Quantum Algorithms" for the next semester (Fall2023) is now visible in the UZH and ETH catalogs. The lecture notes are almost ready, and this is the detailed course content. If you are a Master or PhD student in Zurich, consider booking the course :)

Uhlmann's theorem states that the fidelity of two states rho and sigma can be expressed in terms of their purifications (where the fidelity simplifies). In arxiv.org/abs/2502.01749 we (with Giulia Mazzola and Renato Renner) generalize Uhlmann's theorem to Rényi relative entropies.
