The Quantum Approximate Optimization Algorithm (QAOA) – A Beginner’s Guide
At its core, QAOA is a hybrid quantum-classical algorithm that constructs a special kind of quantum circuit (or “ansatz”) to represent a candidate solution, and then uses a classical optimizer to tweak that circuit for better results. It was introduced in 2014 by Edward Farhi and collaborators as an algorithm…
