Pasqal base classes for emulators

Emu-MPS

EMU-MPS is a Pulser backend, designed to EMUlate the dynamics of programmable arrays of neutral atoms, with matrix product states (MPS). It allows users to increase the number of qubits and reduce computation time.

Join us on Slack or by e-mail to give us feedback about how you plan to use Emu-MPS or if you require specific feature-upgrades.

Getting started

You can install from source, or download the package from the private pypi registry that pasqal maintains in gitlab. For developers, we recommend installing from source, for users we recommend installing from the registry.

Warning: installing emu-mps will update pulser-core

We always recommend using a virtual environment.

Click me to see how it is done

Create a virtual environment using python

python -m venv .venv

Or

python -m venv /path/to/new/virtual/environment

Replace /path/to/new/virtual/environment with your desired directory path.

Then activate the environment On linux or MacOS

source /path/to/new/virtual/environment/bin/activate

While on Windows it's

C:\> /path/to/new/virtual/environment/Scripts/activate

Remember to replace /path/to/new/virtual/environment with the actual path to your virtual environment. Once the environment is activated, you can clone emu_mps and install it using

installing from the registry

When pip is configured to know about the pasqal registry, Emu-MPS installs as

pip install emu-mps

When pip is not already configured, the easiest way to do so, is to add a file ~/.config/pip/pip.conf containing:

[global]
extra-index-url=https://gitlab.pasqal.com/api/v4/projects/597/packages/pypi/simple
                possible.other.urls

As this shows, it is also possible to have multiple extra repositories configured. Note that the order is not important.

It is also possible to add the extra-index-url to the pip install command directly, if you somehow don't want to create a pip.conf file.

installing from source

git clone this repository or download

Then, cd into the root folder of the repo and type

pip install -e .

Guidelines for developers

We recommend using an environment, git clone the repository, then inside the `emu_mps` folder

pip install -e .

Also, the installation of pytest, nbmake, pre-commit.

Do not forget to run the unit test suite by simply running pytest command.

Another way can be using hatch.

virtual environment with hatch

python -m pip install hatch
python -m hatch -v shell

When inside the shell with development dependencies, install first the pre-commit hook:

pre-commit install
