Benchmarking dynamical-structure-factor protocols in programmable neutral-atom geometries
Matteo Grotti, Sergi Julià-Farré, Elisa Ercolessi +1
The dynamical structure factor is a central observable in condensed-matter physics, providing direct insight into the excitation spectrum and dynamical response of quantum material…
A digital Rydberg simulation of dynamical quantum phase transitions in the Schwinger model
Domenico Pomarico, Federico Dell'Anna, Riccardo Cioli +4
We present the simulation of the quench dynamics of the Z3 Schwinger model, that describes an approximation of one-dimensional Quantum Electrodynamics, on a digital noisy Rydberg a…
Quantum Natural Gradient optimizer on noisy platforms: QAOA as a case study
Federico Dell'Anna, Rafael Gomez-Lurbe, Armando Perez +1
We investigate the performance of the Quantum Natural Gradient (QNG) optimizer in the presence of noise. Specifically, we evaluate the efficacy of QNG within the Quantum Approximat…
Quantum error mitigation in optimized circuits for particle-density correlations in real-time dynamics of the Schwinger model
Domenico Pomarico, Mahul Pandey, Riccardo Cioli +5
Quantum computing gives direct access to the study of real-time dynamics of quantum many-body systems. In principle, it is possible to directly calculate non-equal-time correlation…
Approximate inverse measurement channel for shallow shadows
Riccardo Cioli, Elisa Ercolessi, Matteo Ippoliti +2
Classical shadows are a versatile tool to probe many-body quantum systems, consisting of a combination of randomised measurements and classical post-processing computations. In a r…
