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 entanglement

Entanglement is probably one of the most interesting of the three quantum computing principles. This is mainly because it still baffles physicists and scientists to this day, with many taking different philosophical sides on the discussion. I won't bore you with the details, but I will definitely provide you with enough information for you to understand what entanglement is, but not to have a way to prove it. Yes, it sounds confusing, but believe me, the devil is in the detail and there just isn't enough space for us to formulate a comprehensive answer to how entanglement works. But enough of that – let's get to work!

Quantum entanglement, or just entanglement, is simply defined as a quantum mechanical phenomenon that occurs when two or more particles have correlated states. What this, in essence, means is that if you have two particles or, for our purposes, qubits, that are entangled, this means that when we measure one qubit, we...
