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.

Understanding quantum circuits

In previous chapters, you had some exposure to quantum circuit operations in order to understand some of the basic quantum components. These basic operations included creating a quantum circuit, applying quantum gates to the circuit, and executing the circuit on a simulator.

We will now take a deeper look into quantum circuits to better understand what properties and functionalities are available to us to not just execute these circuits on a real device but to do so as optimally as possible. In this section, we will learn how to extract circuit properties, such as circuit depth, width, size, and obtaining the number of actual operators. Let's first start by reviewing the various forms of creating a quantum circuit.

Creating a quantum circuit

There are various ways to create a quantum circuit, each depending on how much information you need throughout your circuit. For example, would you access either the quantum or classical registers? Up...
