Energy gap of quantum spin glasses: a projection quantum Monte Carlo study
L. Brodoloni, G. E. Astrakharchik, S. Giorgini +1
The performance of quantum annealing for combinatorial optimization is fundamentally limited by the minimum energy gap encountered at quantum phase transitions. We investigate…
Adaptive-basis sample-based neural diagonalization for quantum many-body systems
Simone Cantori, Luca Brodoloni, Edoardo Recchi +3
Accurately estimating ground-state energies of quantum many-body systems is still a challenging computational task because of the exponential growth of the Hilbert space with the s…
Spin-glass quantum phase transition in amorphous arrays of Rydberg atoms
L. Brodoloni, J. Vovrosh, S. Julià -Farré +2
The experiments performed with neutral atoms trapped in optical tweezers and coherently coupled to the Rydberg state allow quantum simulations of paradigmatic Hamiltonians for quan…
Zero-temperature Monte Carlo simulations of two-dimensional quantum spin glasses guided by neural network states
L. Brodoloni, S. Pilati
A continuous-time projection quantum Monte Carlo algorithm is employed to simulate the ground state of a short-range quantum spin-glass model, namely, the two-dimensional Edwards-A…
