# Basic Quantum Simulator

In this lesson, we put together everything we have learned so far and create a basic quantum computing simulator.

In the last chapter, we learned the representation for quantum states, gates, and operations in **NumPy**. Now, we shall put together all those pieces and create a basic quantum computing simulator that runs small quantum circuits. As stated at the beginning of the chapter, this exercise of creating our own quantum simulator from scratch cements the understanding of the underlying mathematics and principles of quantum computing before we formally begin our discussion of practical quantum algorithms.

In the following subsections, we will be building the simulator one step at a time. We will be going through the various function definitions and will look at the solution at the end of this lesson.
