Unsupervised Machine Learning on Rigetti 19Q with Forest 1.2

This machine learning algorithm is implemented using the quantum approximate optimization algorithm [0]. I encourage you to read their research paper [1]. It not only contains some interesting ideas about how to use a quantum computer for machine learning applications; but also some information about their 19 qubit processor.

These demos are cool but really highlight the fact that we are decades away from quantum computers that perform useful work.. So far all I've seen are parlor tricks.
