Experimental demonstration of the absence of noise-induced barren plateaus using information content landscape analysis
Sebastian Schmitt, Linus Ekstrøm, Alberto Bottarelli +1
Variational quantum algorithms are promising candidates for near-term quantum computing but can be hindered by barren plateaus, where gradients vanish exponentially and optimizatio…
When the center matters: color screening and gluelumps in dihedral lattice gauge theories
Pavel P. Popov, Edoardo Ballini, Alberto Bottarelli +4
Confinement is one of the hallmarks of quantum chromodynamics (QCD), but its first-principles characterization remains elusive. We show that discrete non-Abelian lattice gauge theo…
Quantum Resources in Non-Abelian Lattice Gauge Theories: Nonstabilizerness, Multipartite Entanglement, and Fermionic Non-Gaussianity
Gopal Chandra Santra, Julius Mildenberger, Edoardo Ballini +3
Lattice gauge theories (LGTs) represent one of the most ambitious goals of quantum simulation. From a practical implementation perspective, non-Abelian theories present significant…
Role of Nonstabilizerness in Quantum Optimization
Chiara Capecci, Gopal Chandra Santra, Alberto Bottarelli +2
Quantum optimization has emerged as a promising approach for tackling complicated classical optimization problems using quantum devices. However, the extent to which such algorithm…
Symmetry-enhanced Counterdiabatic Quantum Algorithm for Qudits
Alberto Bottarelli, Mikel Garcia de Andoin, Pranav Chandarana +4
Qubit-based variational quantum algorithms have undergone rapid development in recent years but still face several challenges. In this context, we propose a symmetry-enhanced digit…
Inequality constraints in variational quantum circuits with qudits
Alberto Bottarelli, Sebastian Schmitt, Philipp Hauke
Quantum optimization is emerging as a prominent candidate for exploiting the capabilities of near-term quantum devices. Many application-relevant optimization tasks require the inc…
Formulation of the Electric Vehicle Charging and Routing Problem for a Hybrid Quantum-Classical Search Space Reduction Heuristic
M. Garcia de Andoin, A. Bottarelli, S. Schmitt +3

Quantum routing of information using chiral quantum walks
Alberto Bottarelli, Massimo Frigerio, Matteo G. A. Paris
We address routing of classical and quantum information over quantum network, and show how to exploit chirality to achieve nearly optimal and robust transport. In particular, we pr…
