Keeps track of the physical parameters necessary for describing the system.\n2. Using these parameters, constructs a function that quickly computes the system's Hamiltonian as a function of time.\n\nThe functional form of the Hamiltonian can then be used as input to any of the solvers implemented in\n[`QuantumOptics.timeevolution`](https://qojulia.org/documentation/timeevolution/timeevolution/). For more information see:\n\n+ Main code: [https://github.com/HaeffnerLab/IonSim.jl/tree/master/src](https://github.com/HaeffnerLab/IonSim.jl/tree/master/src)\n+ Documentation: [https://docs.ionsim.org](https://docs.ionsim.org)\n+ Examples: [https://examples.ionsim.org](https://examples.ionsim.org)\n+ Benchmarks: (coming soon)\n\nIf you have an idea for how to improve IonSim, need some help getting things working or have any other IonSim-related questions feel free to open a GitHub issue.\n\n## How to use\n\n1. Install Julia ([instructions here](https://julialang.org/downloads/)).\n2. Open up a Terminal session and fire up the [Julia REPL](https://docs.julialang.org/en/v1/stdlib/REPL/#The-Julia-REPL-1) with\n```bash\n$ julia\n```\n(*If using Windows it's easier to start a REPL with the julia executable available after installation.*)\n\n3. Now run\n```julia\njulia\u003e using Pkg\njulia\u003e Pkg.add(\"IonSim\")\njulia\u003e Pkg.add(\"IJulia\")\n```\nThe last line adds Jupyter compatibility, so you'll have the option to start a Julia kernel from Jupyter notebook. This is the suggested way\nto interact with IonSim.\n\n### Updating IonSim\n\nIonSim.jl is a work in progress. You can update your local code to the most recent version\nwith the following:\n\n```julia\njulia\u003e using Pkg\njulia\u003e Pkg.update(\"IonSim\")\n```\n\n### Extra Linux notes\n* Extract the downloaded file\n* copy to `/opt` with:\n\n```bash\n$ sudo cp -r julia-1.3.1 /opt/\n```\n(replacing `julia-1.3.1` with the appropriate version)\n* then create a symbolic link in `/usr/local/bin` with\n```bash\n$ sudo ln -s /opt/julia-1.3.1/bin/julia /usr/local/bin/julia\n```\n\n## Development\n\nIf you want to run IonSim locally:\n* Open up the Julia REPL\n```bash\n$ julia\n```\n* Open the package manager by pressing `]`\n* Run the following:\n```julia\npkg\u003e dev IonSim\n```\nThis will clone a version of this repo in `~/.julia/dev/IonSim/`. Then when you make changes to that repo, it will be immediately reflected when using Julia.\n\nYou can run tests with\n```julia\npkg\u003e test IonSim\n```\n\nDon't forget to format the code! `./scripts/format.sh`\n\nTo go back to the version in the registry, use\n```julia\npkg\u003e free IonSim\n```\n\nIn order to update the IonSim.jl version that lives in the Julia general registry, change the version number in the Project.toml file, commit the changes and then add a comment to the commit that reads:\n```\n@JuliaRegistrator register\n```\n\nIf you have any questions, please make a GitHub issue.\n\n[license-url]: https://github.com/HaeffnerLab/IonSim.jl/blob/master/LICENSE.md\n[license-badge]: https://img.shields.io/badge/License-MIT-green.svg\n\n[codecov-url]: https://codecov.io/gh/HaeffnerLab/IonSim.jl\n[codecov-badge]: https://codecov.io/gh/HaeffnerLab/IonSim.jl/branch/master/graph/badge.svg\n\n[twitter-url]: https://twitter.com/Berkeley_ions\n[twitter-badge]: https://img.shields.io/twitter/follow/Berkeley_ions.svg?style=social\u0026label=@Berkeley_ions\n\n[logo-url]: https://github.com/HaeffnerLab/IonSim.jl/blob/media/smallest_logo.png?raw=true\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhaeffnerlab%2Fionsim.jl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fhaeffnerlab%2Fionsim.jl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fhaeffnerlab%2Fionsim.jl/lists"}
