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.

Chapter 10: Executing Circuits Using Qiskit Aer

Aer is a provider of high-performance backends that can be used to execute quantum circuits. The various backend simulators available can be used in unique ways where each can provide various information pertaining to your circuit. Aer also provides a variety of tools that can be leveraged to construct noise models to simulate various errors that occur on real quantum devices. These tools are very helpful should you need to compare the difference between your results from an ideal simulator and that which replicates the effects of noise from a quantum device.

Both the simulators, and tools such as the noise model, will help you understand the reasons for some of the effects on your results as well as provide insights should you later want to mitigate those errors yourself.

The following topics will be covered in this chapter:

  • Understanding the differences between the Aer simulators
  • Generating noise models
  • Building...
