Electromagnetism: an intrinsic approach to Hadamard's method of descent
Giuliano Angelone, Elisa Ercolessi, Paolo Facchi +4
We present a systematic geometric framework for the dimensional reduction of classical electromagnetism based on the concept of descent along vector fields of invariance. By explor…

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…
