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.

Shor’s algorithm is the crowning glory in the theory of gate-based quantum computing. Using Shor’s algorithm, a quantum computer can do what no classical computer could ever have time to do. The algorithm quickly finds the period of a coprime powers sequence and uses information about that period to factor unimaginably large numbers. That’s the good news.

The bad news is that the most obvious use of Shor’s algorithm is for unsavory purposes. Many applications in use today include some form of RSA encryption. And with Shor’s algorithm, a hacker can easily break the RSA encryption scheme. For this reason, the National Institute of Standards and Technology (NIST) in the United States has been running an initiative to develop quantum-proof post-quantum cryptography schemes [4]. Someday, in the not-too-distant future, the battle over your security and privacy will be fought with quantum computers and even more robust cryptographic algorithms...
