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.

Qubits don’t plan ahead

In the 1999 movie Mystery Men, one character has the superpower of making himself invisible, but only when no one is looking. For most people, this raises the question, “What good is that superpower?” For me, it raises an entirely different question: “Since no one can witness this character disappearing, is there a way to find out if the character actually disappears?” Can you verify or disprove the existence of something that, by its very nature, is unobservable? Of course, the knee-jerk answer to this question is, “No, you can’t.”

But, in 1964, physicist John Bell wrote a paper [4] in which he proposed an experiment that could put an end to hidden-variable theories. Then, in 1982, the team of Alain Aspect, Philippe Grangier, and Gérard Roger performed a convincing version of Bell’s experiment [5].
