Full counting statistics as probe of measurement-induced transitions in the quantum Ising chain
Emanuele Tirrito, Alessandro Santini, Rosario Fazio +1
Non-equilibrium dynamics of many-body quantum systems under the effect of measurement protocols is attracting an increasing amount of attention. It has been recently revealed that…
Nonequilibrium Full Counting Statistics and Symmetry-Resolved Entanglement from Space-Time Duality
Bruno Bertini, Pasquale Calabrese, Mario Collura +2
Due to its probabilistic nature, a measurement process in quantum mechanics produces a distribution of possible outcomes. This distribution - or its Fourier transform known as full…
Thermalization of long range Ising model in different dynamical regimes: a full counting statistics approach
Nishan Ranabhat, Mario Collura
We study thermalization of transverse field Ising chain with power law decaying interaction following a global quantum quench of the transverse field to two different…
Quantum Annealing for Neural Network optimization problems: a new approach via Tensor Network simulations
Guglielmo Lami, Pietro Torta, Giuseppe E. Santoro +1
Quantum Annealing (QA) is one of the most promising frameworks for quantum optimization. Here, we focus on the problem of minimizing complex classical cost functions associated wit…
Spreading of a local excitation in a Quantum Hierarchical Model
Luca Capizzi, Guido Giachetti, Alessandro Santini +1
We study the dynamics of the quantum Dyson hierarchical model in its paramagnetic phase. An initial state made by a local excitation of the paramagnetic ground state is considered.…
Avoiding barren plateaus via transferability of smooth solutions in Hamiltonian Variational Ansatz
Antonio Anna Mele, Glen Bigan Mbeng, Giuseppe Ernesto Santoro +2
A large ongoing research effort focuses on Variational Quantum Algorithms (VQAs), representing leading candidates to achieve computational speed-ups on current quantum devices. The…
Clean two-dimensional Floquet time-crystal
Alessandro Santini, Giuseppe E. Santoro, Mario Collura
We consider the two-dimensional quantum Ising model, in absence of disorder, subject to periodic imperfect global spin flips. We show by a combination of exact diagonalization and…
Thermodynamic symmetry resolved entanglement entropies in integrable systems
Lorenzo Piroli, Eric Vernier, Mario Collura +1
We develop a general approach to compute the symmetry-resolved Rényi and von Neumann entanglement entropies (SREE) of thermodynamic macrostates in interacting integrable systems. O…
Matrix Product States with Backflow correlations
Guglielmo Lami, Giuseppe Carleo, Mario Collura
By taking inspiration from the backflow transformation for correlated systems, we introduce a novel tensor network ansatz which extend the well-established Matrix Product State rep…
