aiqbench analysis
This Python package implements the state-vector-based probabilistic imaginary-time evolution algorithm, offering a practical tool for ground-state preparation in quantum many-body systems. By supporting both shot-based simulations and exact diagonalization benchmarks, it facilitates rigorous performance optimization and spectral function calculations like dynamical structure factors. The software enhances interoperability with existing libraries to streamline real-time evolution studies of strongly correlated electrons.
svPITE: A Python package for the state-vector-based probabilistic imaginary-time evolution algorithm
arXiv:2605.07559v3 Announce Type: replace Abstract: We present a Python package for ground-state preparation based on the probabilistic imaginary-time evolution algorithm, with particular focus on its state-vector-based implementation. A standard shot-based simulation is also supported, and results can be benchmarked against exact diagonalisation via a dedicated wrapper. The package enables efficient tuning of initial parameters, facilitating systematic exploration and optimisation of the method's performance. Starting from the prepared ground state, the strong interoperability with other packages further enables real-time evolution and the computation of spectral functions, such as the spin-spin dynamical structure factor.
