Gaussian process model kernels for noisy optimization in variational quantum algorithms
Luca Arceci, Viacheslav Kuzmin, Rick Van Bijnen
Variational Quantum Algorithms (VQAs) aim at solving classical or quantum optimization problems by optimizing parametrized trial states on a quantum device, based on the outcomes o…
Entanglement of formation of mixed many-body quantum states via Tree Tensor Operators
Luca Arceci, Pietro Silvi, Simone Montangero
We present a numerical strategy to efficiently estimate bipartite entanglement measures, and in particular the Entanglement of Formation, for many-body quantum systems on a lattice…
Optimal working point in digitized quantum annealing
Glen Bigan Mbeng, Luca Arceci, Giuseppe E. Santoro
We present a study of the digitized Quantum Annealing protocol proposed by R. Barends et al., Nature 534, 222 (2016). Our analysis, performed on the benchmark case of a transverse…
Dissipation assisted Thouless pumping in the Rice-Mele model
Luca Arceci, Lucas Kohn, Angelo Russomanno +1
We investigate the effect of dissipation from a thermal environment on topological pumping in the periodically-driven Rice-Mele model. We report that dissipation can improve the ro…
On the dynamics of Simulated Quantum Annealing in random Ising chains
Glen Bigan Mbeng, Lorenzo Privitera, Luca Arceci +1
Simulated Quantum Annealing (SQA), that is emulating a Quantum Annealing (QA) dynamics on a classical computer by a Quantum Monte Carlo whose parameters are changed during the simu…
On the optimal working point in dissipative quantum annealing
Luca Arceci, Simone Barbarino, Davide Rossini +1
We study the effect of a thermal environment on the quantum annealing dynamics of a transverse-field Ising chain. The environment is modelled as a single Ohmic bath of quantum harm…
Dissipative Landau-Zener problem and thermally assisted Quantum Annealing
Luca Arceci, Simone Barbarino, Rosario Fazio +1
We revisit the issue of thermally assisted quantum annealing by a detailed study of the dissipative Landau-Zener problem in presence of a Caldeira-Leggett bath of harmonic oscillat…
