Concluding section 2

This section showed you the possibilities and limitations in this new field of quantum computing. We started by learning about quantum annealing and were introduced to the D-Wave advantage device, which can be used to find the minimum of a QUBO problem. Then, we slowly worked our way through understanding how quantum computers work. We started with qubits, then quantum gates, and eventually more elaborate quantum circuits that can add, subtract, and reveal numbers that are stored in the phase information of the qubits. We showed you how to use a quantum phase adder to determine all possible values of a function. This led to us creating a way to amplify the probability of the minimum cost using the QAOA hybrid algorithm, which requires classical parameter tuning. Finally, we evaluated the practical implementation of this algorithm on various devices.

In the current evolution of quantum computers, there are considerable challenges when it comes to getting results...
