8. Certifying spectral gaps of 1D many-body systems using semidefinite programming

Flavio Baccari

Certifying the presence of a spectral gap of a many-body quantum systems is a fundamental challenge that finds numerous applications across very different fields. In many-body physics, a non-zero gap in the thermodynamic limit indicates properties such as area law scaling of entanglement and exponential decay of correlations, both in 1D [1] and (partially) in 2D [2]. In quantum computing, the...

31. Optimal parametric quantum channels for quantum computing

Giuseppe Clemente (University of Pisa and INFN)

10/29/24, 3:10 PM

I will introduce a framework to represent and optimize parametric quantum channels for quantum computing tasks, discussing the current status of research in non-unitary computation protocols and some of their applications to the investigation of quantum lattice systems.

5. QUnfold: Quantum Annealing for Distributions Unfolding in High-Energy Physics

Simone Gasperini

10/29/24, 3:30 PM

In High-Energy Physics experiments, each detector exhibits a unique signature in terms of efficiency, resolution, and geometric acceptance. The overall effect is that the measured distribution of a given physical observable can be smeared and biased. The unfolding algorithm is the classical statistics technique employed to correct for this distortion, aiming to recover the underlying true...
