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.

Sharing secrets

Alice and Bob want to share a secret. They don’t care what the secret means – the secret doesn’t have to mean anything at all. The secret might be “Bob once spit in Alice’s soup” or it might be “3*%Uw4YM^i44Sq.” The content doesn’t matter, so long as no one else knows it.

So, Alice randomly generates 20 bits and sends them to Bob. (See Figure 5.1.)

Figure 5.1 – Alice sends bits to Bob

What they don’t know is that an eavesdropper (named Eve) listens in on the line. Eve makes copies of the bits and sends them to Bob. (See Figure 5.2.)

Sorry, Alice. Your bits aren’t secret. Back to the drawing board!

Adding Hadamard gates

Alice knows all about quantum computing. So, before she sends her bits, she applies the Hadamard operator to each one. Since the Hadamard operator is its own inverse, Bob...
