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…
