Authors: Altares-Lopez, Sergio; Garcia-Ripoll, Juan Jose; Ribeiro, Angela Journal: EXPERT SYSTEMS WITH APPLICATIONS Publication date: 2024/03/25 DOI: 10.1016/j.eswa.2023.122984 Abstract: A new hybrid system is proposed for automatically generating and training quantum-inspired classifiers on grayscale images by using multiobjective genetic algorithms. It is defined a dynamic fitness function to obtain the smallest circuit complexity and highest [...]

Exploring Quantum Annealing Architectures: A Spin Glass Perspective

Marcelo Castellanos2024-03-27T14:34:55+01:00Tags: Quantum Science & Technology; Optics. |

Authors: Jauma, Gabriel; Garcia-Ripoll, Juan Jose; Pino, Manuel Journal: ADVANCED QUANTUM TECHNOLOGIES Publication date: 2024/03/14 DOI: 10.1002/qute.202300245 Abstract: This work analyzes the spin-glass transition across various Ising models relevant to quantum annealers. By employing the parallel tempering method, the location of the spin-glass phase transition is extrapolated from the pseudo-critical temperature of finite-sized systems. The [...]
