qtealeaves 1.12.5

Quantum TEA's python tensor network library

Quantum TEA: qtealeaves

qtealeaves is a tensor network library with a collection of algorithms for solving Schrödinger and Lindblad equation. The library contains the definition of abstract tensor class and its Numpy/Cupy implementation, classes for various tensor network representations (e.g. matrix product state, tree tensor network, locally-purified tensor network, ...), API for building quantum models, and more.

Relation to other Quantum TEA libraries

Quantum Red TEA: qredtea is a supplementary library for switching between additional tensor backends. While qtealeaves alone provides support for Numpy/Cupy-based tensors, qredtea enables running the simulations with Pytorch, Tensorflow, and Jax. Moreover, it enables switching between standard non-symmetric tensors and Abelian symmetry tensors. qredtea requires qtealeaves as a dependency. To get the right combination of versions for using quantum red tea, install qredtea which automatically has a matching qtealeaves version as a dependency.

Quantum Matcha TEA: qmatchatea is built on top of qtealeaves and is specialized in running quantum circuits with tensor networks. It requires both qtealeaves and qredtea as a dependency. To get the right combination of versions for using quantum matcha tea, install qmatchatea which automatically has a matching qtealeaves version as a dependency.

Installation

The package is available via PyPi and pip install qtealeaves.

After cloning the repository, an local installation via pip is also possible via pip install ..
