Tutorials for ITensors.jl and PastaQ.jl.

ITensorTutorials

This repository contains tutorials for gate evolution and optimization using ITensors.jl and PastaQ.jl.

Tutorial

You should state in the presentation directory, which contains a high level summary and detailed tutorial on gate evolution and optimization in presentation/presentation.pdf, along with code associated with the main parts of the presentation.

The presentation is split up into three primary parts:

1. One-site states and operators in ITensor (presentation/01_one_site.jl).
2. Two-site states and operators in ITensor, include state and circuit optimization (presentation/02_two_site.jl).
3. n-site states and operators in ITensor using MPS (presentation/03_n_site.jl).

Exercises

Exercises can be found in the exercises directory, which contains exercises for finding excited states with DMRG and gradient optimization.
