Summary

In this chapter, you learned all the various ways you can operate on both single and multiple qubits. The operations provide various vector states that each qubit can rotate into. You also learned how to visualize the gates on a circuit and learned to decompose them down to universal gates so you can realize the information that is passed onto the quantum system.

You have now understood how these gates operate on qubits. You now have skills that will greatly help you understand how gates are used in many quantum algorithms to position the vectors in the Hilbert space of each qubit to help resolve various problems.

In the next chapter, we will learn about the Quantum Information Science Kit (Qiskit, pronounced kiss-kit (depending on who you ask, it may also be pronounced kwis-kit). Qiskit provides, besides many of the objects and functions we have been using so far to manipulate qubits, other functionality that helps to create quantum algorithms, to mitigate against noise...
