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.

Reviewing classical logic gates

This section will serve as a refresher for classical logic gates such as AND, OR, NOR, and so on. If you are familiar with this subject, you can either skim through this chapter to refresh your memory or skip it entirely and jump to the next section. Otherwise, let's get logical!

Logic gates are defined as a device, electronic or otherwise, that implements a logical (usually Boolean) operation. Single-bit and two-bit gates generally have one or two inputs, respectively. Each input bit value is a state value of either 0 or 1. The operation carried out on the input varies by the type of gate. Each gate operation is usually described using logic truth tables, as illustrated in the following table:

Table 6.1 – Classical logic gates

The preceding table lists some of the common classical gates, descriptions of the operation that each gate performs on the input state, the result (output) of...
