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.

What are the IBM Quantum® machines?

This section is less of a recipe and rather more of a basic overview of the quantum components and processes that you will be encountering. If you'd rather jump ahead and start coding right away, then go to the next recipe.

With Qiskit®, you can run your quantum programs on two types of quantum computers: simulators and IBM Quantum® hardware. The simulators run either locally or in the cloud on IBM hardware. Generally speaking, running a simulator in the cloud gives you greater power and performance; ibmq_qasm_simulator – available online – lets you run fairly deep quantum programs on up to 32 qubits. Your local simulator performance depends on your hardware; remember that simulating a quantum computer gets exponentially harder with each qubit added.

The actual IBM quantum computer hardware is located in an IBM lab and is accessed through the cloud. There are good reasons for this, so let's walk through...
