Readme Contributing License

quimb is an easy but fast python library for 'quantum information many-body' calculations, focusing primarily on tensor networks. The code is hosted on github, and docs are hosted on readthedocs. Functionality is split in two:

The quimb.tensor module contains tools for working with tensors and tensor networks. It has a particular focus on automatically handling arbitrary geometry, e.g. beyond 1D and 2D lattices. With this you can:

construct and manipulate arbitrary (hyper) graphs of tensor networks
automatically contract, optimize and draw networks
use various backend array libraries such as jax and torch via autoray, including symmetries and fermions via symmray
run specific MPS, PEPS, MERA and quantum circuit algorithms, such as DMRG & TEBD

tensor pic

The core quimb module contains tools for reference 'exact' quantum calculations, where the states and operator are represented as either numpy.ndarray or scipy.sparse matrices. With this you can:

construct operators in complicated tensor spaces
find groundstates, excited states and do time evolutions, including with slepc
compute various quantities including entanglement measures
take advantage of numba accelerations
stochastically estimate $\mathrm{Tr}f(X)$ quantities
