Overview of this book

Navigate the quantum computing spectrum with this book, bridging the gap between abstract, math-heavy texts and math-avoidant beginner guides. Unlike intermediate-level books that often leave gaps in comprehension, this all-encompassing guide offers the missing links you need to truly understand the subject. Balancing intuition and rigor, this book empowers you to become a master of quantum algorithms. No longer confined to canned examples, you'll acquire the skills necessary to craft your own quantum code. Quantum Computing Algorithms is organized into four sections to build your expertise progressively. The first section lays the foundation with essential quantum concepts, ensuring that you grasp qubits, their representation, and their transformations. Moving to quantum algorithms, the second section focuses on pivotal algorithms — specifically, quantum key distribution and teleportation. The third section demonstrates the transformative power of algorithms that outpace classical computation and makes way for the fourth section, helping you to expand your horizons by exploring alternative quantum computing models. By the end of this book, quantum algorithms will cease to be mystifying as you make this knowledge your asset and enter a new era of computation, where you have the power to shape the code of reality.

Programming a quantum computer

Quantum computers don’t run independently. They receive input from classical computers and provide output to classical computers. In a sense, there’s no such thing as completely independent quantum computing. All quantum computing is part of a larger technology called hybrid computing.

When you work with quantum computers, you write code that runs on a classical computer. Based on your code, the classical computer feeds instructions to the quantum computer. There are many programming platforms designed specifically for quantum computing. They include Q# from Microsoft, Cirq from Google, OpenQASM from IBM, Ocean from D-Wave, and PennyLane, which is maintained by Xanadu.

In this book, we program using Qiskit – an open source software development kit. Qiskit (pronounced KISS-kit) is part of IBM’s family of quantum computing initiatives. Using Qiskit, you can run code for quantum computers on many different devices. Some...
