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…
