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.

Chapter 5, A Fanciful Tale about Cryptography

      1. Send information about any errors that you find to [email protected].
      2. Send information about any errors that you find to [email protected].
      3. If Eve measures Alice’s qubits, then Alice and Bob will know about it. So, Alice and Bob won’t use any of those qubits as their encryption key. So, if Eve knows some of Alice’s zeros and ones, that information won’t be useful to her.
      4. The following example illustrates the use of the right-distributive law for tensor products:
      1. When we cross-multiply, we use both the left- and right-distributive laws. In the following equations, one step uses the right-distributive law:

      And the next step uses the left-distributive law:

      We use the scalar multiplication law when we combine two qubits’ scalars. Here’s an example:

      1. You can code the circuit...
