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 3: IBM Quantum Experience® – Quantum Drag and Drop

Something pretty amazing happened in the cloud in early 2016; a new type of computer opened its arms to the world—a programmable quantum computer.

In this chapter, we will talk briefly about the early history of IBM Quantum Experience®, how to get there, and how to open a user account. We will take a look at the drag-and-drop user interface for programming the IBM quantum computers (Circuit Composer).

Also, we will take a quick peek at how you can move back and forth between IBM Quantum Experience® and Qiskit® by using the underlying OpenQASM coding.

In this chapter, we will cover the following recipes:

  • Introducing IBM Quantum Experience®
  • Building quantum scores with Circuit Composer
  • Tossing a quantum coin
  • Moving between worlds

We will not stay long here; just long enough to scratch the surface, present a quantum circuit we will play with later in Chapter...
