Description:

PennyLaneRigetti 0.36.0

The PennyLane Rigetti plugin allows different Rigetti devices to work with
PennyLane — the wavefunction simulator, the Quantum Virtual Machine (QVM), and Quantum Processing Units (QPUs).
pyQuil is a Python library for quantum programming using the
quantum instruction language (Quil) — resulting quantum programs can be executed using the
Rigetti Forest SDK and Rigetti Quantum Cloud Services (QCS).
PennyLane is a cross-platform Python library for quantum machine
learning, automatic differentiation, and optimization of hybrid quantum-classical computations.
The plugin documentation can be found here: https://docs.pennylane.ai/projects/rigetti.

Features

Provides four devices to be used with PennyLane: rigetti.numpy_wavefunction,
rigetti.wavefunction, rigetti.qvm, and rigetti.qpu. These provide access to the pyQVM
Numpy wavefunction simulator, pyQuil wavefunction simulator, quantum
virtual machine (QVM), and quantum processing units (QPUs) respectively.
All provided devices support all core qubit PennyLane operations and observables.

Installation
PennyLane-Rigetti, as well as all required Python packages mentioned above, can be installed via pip:
$ python -m pip install pennylane-rigetti
Make sure you are using the Python 3 version of pip.
Alternatively, you can install PennyLane-Rigetti from the source code by navigating to the top-level directory and running
$ python setup.py install

Dependencies
PennyLane-Rigetti requires the following libraries be installed:

Python >=3.9

as well as the following Python packages:

PennyLane >=0.18.0
pyQuil >=3.0.0, <4.0.0

If you currently do not have Python 3 installed, we recommend
Anaconda for Python 3, a distributed version
of Python packaged for scientific computation.
Additionally, if you would like to compile the quantum instruction language (Quil) and run it
locally using a quantum virtual machine (QVM) server, you will need to download and install the
Forest software development kit (SDK):

Forest SDK

Alternatively, you may sign up for Rigetti’s Quantum Cloud Services (QCS) which will allow you to compile your
quantum code and run on real QPUs. Note that this requires a valid QCS account and the QCS CLI:

Tests
To test that the PennyLane-Rigetti plugin is working correctly you can run
$ make test
in the source folder.

Documentation
To build the HTML documentation, go to the top-level directory and run:
$ make docs
The documentation can then be found in the doc/_build/html/ directory.
