Grove is a repository to showcase quantum programs developed using Forest. It includes the quantum Fourier transform, phase estimation, the quantum approximate optimization algorithm, and others.


The quantum approximate optimization algorithm is a great example of a classical/quantum hybrid algorithm that does combinatorial optimization. Included in Grove is an implementation of this algorithm using Forest.
