Optimization is ubiquitous in industry and research. However, many optimization problems of interest are hard to solve. In this lecture Lucia, Julien and Daniel show you how quantum computing approaches combinatorial optimization problems. You will learn how to solve optimization problems on quantum computers and the algorithms to do so. The course is aimed at university level students with a technical background. Prior knowledge of quantum computing is helpful but not necessary.

Course information
Optimization is ubiquitous in industry and research and has many different applications. Portfolio construction, supply chain, and maximum-cut are all examples of optimization problems. However, many optimization problems of interest are hard to solve. Quantum computing is a growing and novel computing paradigm in which information is processed with the laws of quantum mechanics. Crucially, it has the potential to tackle hard optimization problems.
This course is aimed at professionals and students with a technical background who are interested in quantum optimization.
In this course you will learn how quantum computers tackle hard optimization problems. For example, you will learn about adiabatic quantum computing and variational algorithms on gate-based quantum computers. After the course, you will be able to understand state-of-the-art research in quantum optimization.
The workload for the course is approximately 3-5 hours per week, depending on prior knowledge.
The course consists of short study videos accompanied by tests, and a final exam. You must achieve at least 50% of the points for a certificate of achievement, with the final exam accounting for 50% of the points and have accessed at least 50% of the resources to receive a certificate of attendance.
The prerequisites for the course are basic knowledge of quantum information. Knowledge of classical optimization is not required but may help you better appreciate some of the course material.

Intro
Week 1:
In the first week you will learn the basics of how to carry out optimization tasks on quantum computers. We will learn about optimization classes, and in particular, quadratic unconstrained binary optimization. Next, we learn how to encode such problems in Ising Hamiltonians and how to tackle them with quantum annealing and variational algorithms such as quantum approximate optimization.Week 2:
In the second week we will study improvements and extensions to the algorithms from week 1 and how they can be executed on superconducting qubits. You will also learn about a non-variational approach to optimization problems on a quantum computer. Finally, there are two interviews that wrap up the course, where we discuss possible applications, challenges and an outlook for quantum optimization.Final exam
