Summary

In this chapter, we covered various simulators. You now have the skills to leverage various simulators to simulate running circuits on a quantum computer and obtain specific content from the circuits, such as state vectors, a unitary matrix, and any scheduled pulses.

We also covered various visualization techniques. The skills that you have gained will help you visualize the various pieces of information from the simulator, such as visualizing the state and phase information of a qubit using the QSphere and plotting state vector graphs. And finally, we looked into the noise models that Aer provides by either extracting the noise from an existing quantum computer, or creating our own noise models and applying them to the simulators.

In the next chapter, we will learn how to characterize and mitigate noise using Ignis. This will allow us to optimize the performance of the quantum computer and increase its computational power. We will also learn how to measure a quantum...
