Exploring pathways towards quantum advantage in quantum chemistry: the case of a molecule with half-Möbius topology
Samuele Piccinelli, Stefano Barison, Alberto Baiardi +8
We report quantum chemistry calculations performed on superconducting quantum processors for a molecule exhibiting the half-Möbius electronic topology originally introduced by Ron…
Quantum chemistry with provable convergence via randomized sample-based Krylov quantum diagonalization
Samuele Piccinelli, Alberto Baiardi, Stefano Barison +12
Quantum algorithms based on classical processing of individual samples have recently emerged as the most effective and robust methods to approximate ground-state wave functions of…
Classically Prepared, Quantumly Evolved: Hybrid Algorithm for Molecular Spectra
Alessandro Santini, Stefano Barison, Filippo Vicentini
We introduce a hybrid classical-quantum algorithm to compute dynamical correlation functions and excitation spectra in many-body quantum systems, with a focus on molecular systems.…
Local fermion-to-qudit mappings: a practical recipe for four-level systems
Rodolfo Carobene, Stefano Barison, Andrea Giachero +1
In this paper, we present a new set of local fermion-to-qudit mappings for simulating fermionic lattice systems. We focus on the use of multi-level qudits, specifically ququarts. T…
Quantum-centric computation of molecular excited states with extended sample-based quantum diagonalization
Stefano Barison, Javier Robledo Moreno, Mario Motta
The simulation of molecular electronic structure is an important application of quantum devices. Recently, it has been shown that quantum devices can be effectively combined with c…
