openqaoa-core 0.2.0

OpenQAOA is a python open-source multi-backend Software Development Kit to create, customise and execute the Quantum Approximate Optimisation Algorithm (QAOA) on Noisy Intermediate-Scale Quantum (NISQ) devices, and simulators

OpenQAOA-Core

OpenQAOA is a multi-backend python library for quantum optimization using QAOA on Quantum computers and Quantum computer simulators. This package is part of a set of OpenQAOA plug-ins and forms the core functionality of the package. It includes all backend agnostic elements of the QAOA process. Along with other OpenQAOA plug-in extensions enables users to seemlessly run QAOA computations across multiple Quantum Computers. Additionally, it also comes bundled with Entropica's fast QAOA simulator called vectorized and a unit-depth QAOA analytical simulator (you can find more details in the Getting Started section). Check out OpenQAOA website https://openqaoa.entropicalabs.com/

OpenQAOA is currently in OpenBeta.

Installation instructions

Install via PyPI

You can install the latest version of openqaoa-core directly from PyPi. We recommend creating a virtual environment with python>=3.8 first and then simply pip install openqaoa-core with the following command.

pip install openqaoa-core

Installation instructions for Developers

OpenQAOA-Core does not yet support developer install as a standalone package. If you wish to work in developer mode, please install the entire library. Instructions are available here

Should you face any issue during the installation, please drop us an email at [e-mail] or open an issue!

Getting started

The documentation for OpenQAOA-Core can be found here.

We also provide a set of tutorials to get you started. Among the many, perhaps you can get started with the following ones:

• A notebook showing Analytical Simulator usage
• Introducing EL's fast QAOA simulator
• Discover OpenQAOA's custom parametrizations
• Notebook demonstrating different optimizers to choose from

Key Features

• Build advanced QAOAs. Create complex QAOAs by specifying custom parametrisation, mixer hamiltonians, classical optimisers and execute the algorithm on either simulators or QPUs.

• Recursive QAOA. Run RQAOA with fully customisable schedules on simulators and QPUs alike.

• QPU access. Built in access for IBM Quantum, Rigetti QCS, Amazon Braket and Azure Quantum (Please install the OpenQAOA plugin corresponding to the QPU platform for running QAOA on these devices).

Available devives

Devices are serviced both locally and on the cloud. For the IBM Quantum experience, the available devices depend on the specified credentials. For QCS and Amazon Braket, the available devices are listed in the table below:

Device location	Device Name
local	['vectorized', 'analytical_simulator']
