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.

What is quantum computing?

Quantum reality is very strange.

Imagine a spinning wheel that’s turning neither clockwise nor counterclockwise. Just by looking at the wheel, you set up a relationship between yourself and the wheel, and this makes the wheel turn in one direction or another.

Imagine two friends who travel to opposite ends of the Milky Way galaxy. Whatever one randomly decides to say upon landing on a distant planet, the other feels compelled to say too.

That’s the world of quantum mechanics. It’s what makes quantum computing so fascinating.

Here’s how we distinguish quantum computing from classical computing:

  • Classical computing: A computational model in which the fundamental unit for calculation is a binary bit. Each bit’s value is either 0 or 1.

Every laptop, server, workstation, and smartphone is a kind of classical computer. Even the Frontier supercomputer with 600,000 cores in Oak Ridge, Tennessee is a classical...
