qtealeaves of the Quantum TEA library with version v1.12.5 containing tensor network methods to simulate many-body quantum systems. The work is based on the following references, please consider citing them in addition to the software package depending on your use case: 1) Pietro Silvi et al., "The Tensor Networks Anthology: Simulation techniques for many-body quantum lattice systems", SciPost Physics Lecture Notes, 008 (2019) 2) Simone Montangero, "Introduction to Tensor Network Methods", Springer (2018) 3) For TTOs: Nora Reinić et al., "Finite-temperature Rydberg arrays: quantum phases and entanglement characterization", Physical Review Research 6 (3), 033322 (2024). 4) For sampling: Marco Ballarin et al., "Optimal sampling of tensor networks targeting wave function's fast decaying tails", arXiv:2401.10330 (2024) You find a bibtex amongst the files. We provide additional information on how to run qtealeaves via the Quantum TEA homepage. (Authors are in alphabetical order.)
