ITensor/ITensor

Code

Homepage: http://itensor.org/

An efficient and flexible C++ library for performing tensor network calculations.

The foundation of the library is the Intelligent Tensor or ITensor. Contracting ITensors is no harder than multiplying scalars: matching indices automatically find each other and contract. This makes it easy to transcribe tensor network diagrams into correct, efficient code.

Installation instructions can be found in the INSTALL file.
