Local simulation of noise models
First, we must distinguish between the three naming conventions we will use during this chapter and the following ones. Previously, we talked about how quantum algorithms can be run on a classical device before being sent to a real quantum device, but there are some different ways in which this classical execution can be done. Problems such as the ones we have posed have been around for a while, and classical computing has evolved in many different ways to bring solutions to the technology at hand during this time. As we will see, this may also bring some challenges related to the specifics of the different classical setups we will cover. Mimicking quantum mechanical evolution is a non-trivial task; that was how quantum computing was proposed as a potential solution.
Simulators are the classical means of processing information in the way an ideal quantum computer would do so. Recall that quantum information theory is not a new task brought about...
