#### Description

Quantum computing has potential to efficiently solve combinatorial optimization problems. Recent advances in both hardware and algorithm development have made it possible to solve small problems on modern quantum computers. Combinatorial optimization problems (especially NP-hard problems) are of particular interest, since for many of these problems efficient classical algorithms are not known. One such problem is MaxCut on graphs. In this minitutorial, we will introduce the MaxCut problem and explain how it can be solved on IBM quantum computers available on the cloud today using the Qiskit framework. Our presentation will assume little to no prior knowledge of quantum computation. Moreover, we will provide examples of how more complicated problems can be solved using the QAOA (Quantum Approximate Optimization Algorithm). The tutorial will be interactive and will use Jupyter notebooks to explain step by step how to formulate and implement algorithms in the Ising Hamiltonian form.

Participants are encouraged to bring their own laptops.

The recommended way to run the hands-on Jupyter notebooks is using IBM Quantum Experience web interface. Please create an account here before the tutorial (you might have to create an IBM ID if you do not have one). Additional instructions and the hands-on notebook are available here.
