rydiqule 1.1.0

Rydberg Sensor Interactive Quantum Physics Module

The Rydberg Interactive Quantum module is a modelling library designed to simulate the response of a Rydberg atoms to arbitrary input RF waveforms. It also functions as a general master equation solver based on the semi-classical density matrix method.

Installation

Presently, installation is done via pip. See below for detailed instructions.

In all cases, it is highly recommended to install rydiqule in a virtual environment.

Conda/pip installation

If using a conda to provide the virtual environmnet, it can often be advantageous to install as many packages as possible via conda before running the pip installation command.

Assuming you have not already created a separate environment for RydIQule (recommended), run the following to create a new environment:

(base) ~/> conda create -n rydiqule python=3.9
(base) ~/> conda activate rydiqule

RydIQule currently requires python >3.8.

Now install dependencies that are available via conda. To capture as many dependencies as possible, we will add the conda-forge channel at a lower priority.

(rydiqule) ~/> conda config --env --append channels conda-forge
(rydiqule) ~/> conda config --set channel_priority strict
(rydiqule) ~/> conda install numpy scipy matplotlib networkx numba psutil
# ARC specific dependencies available via conda
(rydiqule) ~/> conda install sympy asteval lmfit uncertainties

Now use pip to install rydiqule and remaining dependencies.

# for normal installation
(rydiqule) ~/> pip install rydiqule
# for editable installation, so source can be modified locally
(rydiqule) ~/> pip install -e rydiqule

Pure pip installation

To install normally, run:

pip install rydiqule

This command will use pip to install all necessary dependencies.

To install in an editable way (which allows edits of the source code), run:

pip install -e rydiqule

Confirm installation

Proper installation can be confirmed by executing the following commands in a python terminal.

>>> import rydiqule as rq
>>> rq.about()

Updating an existing installation

Upgrading an existing installation is simple. Simply run the pip installation commands described above with the update flag.

pip install -U rydiqule

This command will also install any new dependencies that are required.

If using an editable install, simply replacing the files in the same directory is sufficient. Though it is recommended to also run the appropriate pip update command as well.

pip install -U -e rydiqule

Dependencies

This package requires installation of the excellent ARC package, which is used to get Rydberg atomic properties. It also requires other standard computation dependenices, such as numpy, scipy, matplotlib, etc. These dependencies will be automatically installed by pip if not already present.

Rydiqule's performance does depend on these depedencies. In particular, numpy can be compiled with a variety of backends that implements BLAS and LAPACK routines that can have different performance for different computer architectures. When using Windows, it is recommended to install numpy from conda, which is built against the IntelMKL and has generally shown the best performance for Intel-based PCs.

Optional timesolver backend dependencies include the numbakit-ode and CyRK packages. Both are available via pip. They can be installed automatically via the optional extras specification for the pip command.

pip install rydiqule[backends]
