Understanding the differences between the Aer simulators
The IBM Quantum Experience (IQX) has an array of not only real backend quantum devices, but also a multitude of simulators as well, many of which we have used so far in this book. IQX always has the latest Qiskit packages installed. This makes it easy for anyone new to quantum computing to simply log on and start learning and coding right away.
In this section, you will learn about the various Aer simulators, including the differences between them and their distinct features. These features include generating noise models and configuring the simulator backends that allow you to take advantage of modifying their behavior and characteristics to suit your needs.
Of course, you can always install Qiskit locally on your own machine, servers, or any supported device. However, one advantage to using the simulators on IQX is the fact that the server it is installed onto is a pretty large, high-performance system with plenty of...
