TL;DR: Santoro et al. as mentioned in this paper revisited the question of when quantum speedup may be expected for Ising spin glass problems, and they found that even though a better scaling compared to simulated classical annealing can be achieved for QMC simulations, this advantage is due to time discretization and measurements which are not possible on a physical quantum-annealing device.

TL;DR: This work presents a C++ Monte Carlo class library for the automatic parallelization of Monte Carlo simulations and discusses the advantages of object-oriented design in the development of this library.

TL;DR: This work shows that by using a hybrid quantum-classical algorithm that incorporates the power of a small quantum computer into a framework of classical embedding algorithms, the electronic structure of complex correlated materials can be efficiently tackled using a quantum computer.

TL;DR: It is shown that the character of the quantum phase transition is radically altered from the corresponding nondissipative model and the double well coupled to a dissipative heat bath with linear friction to form a new quantum criticality which is independent of dissipation strength.

TL;DR: In this article, a tensor network (CGTN) ansatz is proposed to capture the electron correlation within a molecule of arbitrary structure, which is applied to the energy splitting of states of different spins for methylene and strongly correlated ozone molecule at a transition state structure.
