Topological entanglement properties of disconnected partitions in the Su-Schrieffer-Heeger model
Tommaso Micallo, Vittorio Vitale, Marcello Dalmonte +1
We study the disconnected entanglement entropy, , of the Su-Schrieffer-Heeger model. is a combination of both connected and disconnected bipartite entanglement entropies…

Entanglement topological invariants for one-dimensional topological superconductors
Pierre Fromholz, Giuseppe Magnifico, Vittorio Vitale +2
Entanglement is known to serve as an order parameter for true topological order in two-dimensional systems. We show how entanglement of disconnected partitions defines topological…

Assessing the quantumness of the annealing dynamics via Leggett Gargs inequalities: a weak measurement approach
V. Vitale, G. De Filippis, A. De Candia +3
Adiabatic quantum computation (AQC) is a promising counterpart of universal quantum computation, based on the key concept of quantum annealing (QA). QA is claimed to be at the basi…
