TL;DR: A large-scale programmable quantum simulation is described, using a D-Wave quantum processor to simulate a two-dimensional magnetic lattice in the vicinity of a topological phase transition.

TL;DR: In this paper, the authors report on experimental observations of equilibration in quantum annealing simulations, measured on up to 1440 qubits with microsecond resolution, and demonstrate that PIMC does not simulate QA dynamics even for sign-problem-free Hamiltonians, and that nearterm quantum devices can be used to accelerate computational tasks of practical relevance.

TL;DR: In this paper , the authors demonstrate coherent evolution through a quantum phase transition in the paradigmatic setting of a one-dimensional transverse-field Ising chain, using up to 2,000 superconducting flux qubits in a programmable quantum annealer.

TL;DR: In this article, two superconducting flux qubits are coupled via two canonically conjugate degrees of freedom (charge and flux) to achieve a nonstoquastic Hamiltonian.

TL;DR: The observed scaling advantage in the quantum simulation over the classical approach of path-integral Monte Carlo fixed-Hamiltonian relaxation with multiqubit cluster updates demonstrates that near-term quantum devices can be used to accelerate computational tasks of practical relevance.
