Learn Quantum Computing with Python and IBM Quantum Experience

By: Robert Loredo

Overview of this book

IBM Quantum Experience is a platform that enables developers to learn the basics of quantum computing by allowing them to run experiments on a quantum computing simulator and a real quantum computer. This book will explain the basic principles of quantum mechanics, the principles involved in quantum computing, and the implementation of quantum algorithms and experiments on IBM's quantum processors. You will start working with simple programs that illustrate quantum computing principles and slowly work your way up to more complex programs and algorithms that leverage quantum computing. As you build on your knowledge, you’ll understand the functionality of IBM Quantum Experience and the various resources it offers. Furthermore, you’ll not only learn the differences between the various quantum computers but also the various simulators available. Later, you’ll explore the basics of quantum computing, quantum volume, and a few basic algorithms, all while optimally using the resources available on IBM Quantum Experience. By the end of this book, you'll learn how to build quantum programs on your own and have gained practical quantum computing skills that you can apply to your business.

Creating a quantum circuit using the Composer

In this section, we will review the Composer layout so that you can understand the functionality and behavior of the Composer when creating or editing your quantum circuits. Here, you will also create a few circuits, leveraging the visualization features from the Composer to make it easy for you to understand how quantum circuits are created. So, let's start at the beginning: by launching the Composer editor.

Launching the Composer editor

To create a quantum circuit, let's first start by opening up the Circuit Composer. To open the Composer view, click on the Circuit Composer icon located on the left panel as shown in the following screenshot:

Figure 2.1 – Launching the Circuit Composer (left panel)

Now that you have the Composer open, let's take a tour of what each component of the Composer editor provides you with.
