QAOA.jl

CI DOI DOI

This package implements the Quantum Approximate Optimization Algorithm and the Mean-Field Approximate Optimization Algorithm.

Installation

To install, use Julia's built-in package manager

julia> ] add QAOA

Documentation & Examples

Our docs can be found here. Examples showcasing the use of QAOA.jl are also presented in our examples folder.

Benchmarks

QAOA.jl also supports gradient optimization via automatic differentiation. Below is a comparison of run times between PennyLane [@PennyLane] and QAOA.jl on an Apple M1 processor. The benchmarks are retrieved by performing 128 steps with the respective gradient optimizer on the same instance of size $N$ of the minimum vertex-cover problem.

Support & Contributing

In case you need support or have encountered a problem with the package, you are welcome to create an issue on GitHub. If you would like to contribute to QAOA.jl, you can reach us via PGI-12.
