ITensor

A software library for developing and performing state of the art tensor network calculations.

Welcome to the ITensor organization

This is the ITensor organization. This organization revolves around the Julia and C++ versions of the ITensor library for performing tensor network calculations, along with related Julia and C++ libraries.

The main developers are Matt Fishman and Miles Stoudenmire, please reach out to either of us for questions, comments, issues, or suggestions (or raise issues on a particular repository).
