Install PennyLane

PennyLane supports Python 3.8 or newer.

If you currently do not have Python 3 installed, we recommend Anaconda for Python 3, a distributed version of Python packaged for scientific computation.

                
# install the latest released version of PennyLane
pip install pennylane --upgrade
                
            
                
# install the latest development version of PennyLane
pip install git+https://github.com/PennyLaneAI/pennylane.git#egg=pennylane
                
            
                
# download and install the latest source code from GitHub
git clone https://github.com/PennyLaneAI/pennylane.git
cd pennylane
pip install -e .

Note: if installing from source for development, changes to plugin device registration will require pip install -e . to be re-run to take effect.

Install quantum devices

PennyLane comes with high performance built-in simulators, such as default.qubit, default.mixed, and lightning.qubit. In addition, it supports additional quantum simulators and quantum hardware via an array of plugins. For more details, visit the plugins page.
