Discrete Truncated Wigner Approximationhe Wigner function, a (quasi-)probability distribution in phase space underlying the initial quantum state. This ansatz is called the truncated Wigner approximation and it can be adapted for spin-1/2 systems providing the discrete truncated Wigner approximation. In comparison to mean-field approxima

Conclusions, where general efficient simulation techniques are still missing. We have considered the discrete truncated Wigner approximation (dTWA) as a semi-classical phase-space method[.,.,.], as well as an approach based on quantum Monte Carlo techniques. The latter uses a parametrization of quantum state

RBM-Based Wave Function Parametrization approach using a restricted Boltzmann machine to parametrize quantum state vectors and apply Monte Carlo sampling of those states has been introduced in[.], where representations of ground states and dynamics are found via a variational ansatz.

Standard digital high-performance computing is generally too weak to capture all the necessary details, such that alternative quantum simulation devices have been proposed as a solution. Artif
