Error correction and quantum information spreading on sparse random graphs
Giovanni Cemin, Marin Bukov, Andrea Solfanelli
Quantum error-correcting codes on graph geometries beyond regular euclidean lattices have emerged as a promising route toward robust quantum information processing. A major challen…
(Non-)Traversable Quantum Phase Transitions
Federico Balducci, Paul M. Schindler, Andrea Solfanelli +1
Quantum phase transitions manifest as an abrupt change in the ground state of a many-body system; yet it is an open question whether this sudden change necessarily precludes a cont…
Robust spin-squeezing with random interaction graphs: the lesson from universality
Andrea Solfanelli, Augusto Smerzi, Peter Zoller +1
We establish the conditions under which scalable spin squeezing can be achieved in interacting spin ensembles embedded in arbitrary, inhomogeneous graph geometries. We identify two…
Universality and weak-ergodicity breaking in quantum quenches
Guido Giachetti, Andrea Solfanelli, Nicolò Defenu
Understanding equilibration and universality after sudden quantum quenches remains a central challenge in isolated many-body systems. Persistent oscillations and anomalous scaling…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
The long-range origin of the black hole entropy
Andrea Solfanelli, Francesco Petocchi, Nicolò Defenu
The Sachdev-Ye-Kitaev (SYK) model, has emerged as a powerful tool for exploring the quantum nature of black holes, particularly their residual entropy at zero temperature. In this…
Universal work statistics in long-range interacting quantum systems
Andrea Solfanelli, Nicolò Defenu
We determine the conditions under which the presence of long-range interactions reduce the energy losses due to defect generation during non-adiabatic evolution, crucial for enhanc…
Universality in long-range interacting systems: the effective dimension approach
Andrea Solfanelli, Nicolò Defenu
Dimensional correspondences have a long history in critical phenomena. Here, we review the effective dimension approach, which relates the scaling exponents of a critical system in…
Stabilization of Discrete Time-Crystaline Response on a Superconducting Quantum Computer by increasing the Interaction Range
Andrea Solfanelli, Stefano Ruffo, Sauro Succi +1
The simulation of complex quantum many-body systems is a promising short-term goal of noisy intermediate-scale quantum (NISQ) devices. However, the limited connectivity of native q…
Quantization of integrable and chaotic three-particle Fermi-Pasta-Ulam-Tsingou models
Alio Issoufou Arzika, Andrea Solfanelli, Harald Schmid +1
We study the transition from integrability to chaos for the three-particle Fermi-Pasta-Ulam- Tsingou (FPUT) model. We can show that both the quartic b-FPUT model ( = 0) and the…
Work statistics, quantum signatures and enhanced work extraction in quadratic fermionic models
Alessandro Santini, Andrea Solfanelli, Stefano Gherardini +1
In quadratic fermionic models we determine a quantum correction to the work statistics after a sudden and a time-dependent driving. Such a correction lies in the non-commutativity…
Logarithmic, Fractal and Volume-Law Entanglement in a Kitaev chain with long-range hopping and pairing
Andrea Solfanelli, Stefano Ruffo, Sauro Succi +1
Thanks to their prominent collective character, long-range interactions promote information spreading and generate forms of entanglement scaling, which cannot be observed in tradit…
Observation of partial and infinite-temperature thermalization induced by repeated measurements on a quantum hardware
Alessandro Santini, Andrea Solfanelli, Stefano Gherardini +1
On a quantum superconducting processor we observe partial and infinite-temperature thermalization induced by a sequence of repeated quantum projective measurements, interspersed by…
