Overview of this book

IBM Quantum Experience® is a leading platform for programming quantum computers and implementing quantum solutions directly on the cloud. This book will help you get up to speed with programming quantum computers and provide solutions to the most common problems and challenges. You’ll start with a high-level overview of IBM Quantum Experience® and Qiskit®, where you will perform the installation while writing some basic quantum programs. This introduction puts less emphasis on the theoretical framework and more emphasis on recent developments such as Shor’s algorithm and Grover’s algorithm. Next, you’ll delve into Qiskit®, a quantum information science toolkit, and its constituent packages such as Terra, Aer, Ignis, and Aqua. You’ll cover these packages in detail, exploring their benefits and use cases. Later, you’ll discover various quantum gates that Qiskit® offers and even deconstruct a quantum program with their help, before going on to compare Noisy Intermediate-Scale Quantum (NISQ) and Universal Fault-Tolerant quantum computing using simulators and actual hardware. Finally, you’ll explore quantum algorithms and understand how they differ from classical algorithms, along with learning how to use pre-packaged algorithms in Qiskit® Aqua. By the end of this quantum computing book, you’ll be able to build and execute your own quantum programs using IBM Quantum Experience® and Qiskit® with Python.

Chapter 5: Touring the IBM Quantum® Hardware with Qiskit®

In the previous chapters, we have mainly used built-in and local quantum computer simulators of various forms, but we also connected and ran some of our quantum programs on actual IBM quantum computers. In this chapter, we will take a closer look at these backends, down to the level of actual physical qubits.

We will take a quick tour of the IBM Quantum® lab by using both IBM Quantum Experience® and Qiskit® to access data about the available hardware. Among these things, we will look at the graphical view of the layout of the quantum chips, some physical aspects of quantum computers such as the T1 and T2 decoherence parameters, some basic and advanced error metrics, the way the available qubits can interact among themselves, and more.

In this chapter, we will cover the following recipes:

  • What are the IBM Quantum® machines?
  • Locating the available backends
  • Comparing backends...
