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.

Magic tricks with multi-qubit gates

Imagine this: You send two people to two different grocery stores. Before doing so, you give each an instruction to buy either meat or fish. You don’t say which of the two products either person should buy. When they return from their respective stores, they both return with meat—not fish.

The next day, you do all this again in exactly the same way. “Buy either meat or fish,” you say. On this second day, they both return with fish—not meat. On the third day, they both return with fish again. On the fourth day, they both return with meat. On a given day, you can’t predict whether they’ll both return with meat or both return with fish. But you know one thing for sure: they’ll always return with the same food. What’s more, if you repeat the experiment 100 times, they’ll return approximately half the time with meat and the other half with fish.

Your first guess is that, before...
