Quantum Dynamics and Control with QuantumControl.jl – Example: Optimization of a Perfectly Entangling Quantum Gate

This example notebook was shown in the talk Quantum Dynamics and Control with QuantumControl.jl (Slides) at JuliaCon 2023.

It is a based on the example available at https://juliaquantumcontrol.github.io/GRAPE.jl/stable/examples/perfect_entanglers/

System Prerequisites

• Jupyter Notebook or Lab with the Jupytext extension. The recommended installation method is via Miniforge.

• Julia 1.9.2 with IJulia. To install the appropriate Julia kernel, run

  using IJulia; installkernel("Julia", "--threads=auto", "--project=@.")
  

  in the julia REPL.

Project Instantiation

> julia --project=.
julia> using Pkg
julia> Pkg.instantiate()

Running the Notebook

Start a Jupyter Notebook or Jupyter Lab instance, and open the perfect_entanglers.ipynb file. With the Jupytext extension, you can also directly open the perfect_entanglers.jl file.

Alternatively to using Jupyter, you may also just run the .jl file or execute it line-by-line e.g. with Visual Studio Code.
