Multipartite entanglement in quantum phase transitions
Marco Gabbrielli
This dissertation collects results about witnessing multipartite entanglement in critical spin systems and free-fermion models both at zero and finite temperature.
Multipartite-Entanglement Tomography of a Quantum Simulator
Marco Gabbrielli, Luca Lepori, Luca Pezzè
Multipartite entanglement tomography, namely the quantum Fisher information (QFI) calculated with respect to different collective operators, allows to fully characterize the phase…
Multipartite Entanglement at Finite Temperature
Marco Gabbrielli, Augusto Smerzi, Luca Pezzè
The interplay of quantum and thermal fluctuations in the vicinity of a quantum critical point characterizes the physics of strongly correlated systems. Here we investigate this int…
Multipartite entanglement in topological quantum phases
Luca Pezzè, Marco Gabbrielli, Luca Lepori +1
We witness multipartite entanglement in the Kitaev chain -- a benchmark model of one dimensional topological insulator -- also with variable-range pairing, using the quantum Fisher…
