Entanglement barrier and its symmetry resolution: theory and experiment
Aniket Rath, Vittorio Vitale, Sara Murciano +6
The operator entanglement (OE) is a key quantifier of the complexity of a reduced density matrix. In out-of-equilibrium situations, e.g. after a quantum quench of a product state,…
Symmetry-resolved entanglement detection using partial transpose moments
Antoine Neven, Jose Carrasco, Vittorio Vitale +8
We propose an ordered set of experimentally accessible conditions for detecting entanglement in mixed states. The -th condition involves comparing moments of the partially trans…
Mixed-state entanglement from local randomized measurements
Andreas Elben, Richard Kueng, Hsin-Yuan Huang +8
We propose a method for detecting bipartite entanglement in a many-body mixed state based on estimating moments of the partially transposed density matrix. The estimates are obtain…
Entanglement renormalization and boundary critical phenomena
P. Silvi, V. Giovannetti, P. Calabrese +2
The multiscale entanglement renormalization ansatz is applied to the study of boundary critical phenomena. We compute averages of local operators as a function of the distance from…
Entanglement entropy and quantum field theory: a non-technical introduction
Pasquale Calabrese, John Cardy
In these proceedings we give a pedagogical and non-technical introduction to the Quantum Field Theory approach to entanglement entropy. Particular attention is devoted to the one s…
