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 6, Quantum Networking and Teleportation

      1. In the Quantum operations for teleportation section, we derive the following formula:

      When the initial state of Alice’s qubit is |0, alpha = 1 and beta = 0. So, the formula becomes

      We have four possibilities, and each possibility has three qubits. Alice measures the middle qubit. When that measurement yields the value 1, Bob applies the X gate. So, we have

      No matter what values Alice’s measurements yield, Bob’s qubit is in the |0 state. So the value of Alice’s qubit has been teleported to Bob.

      The calculation is similar when the initial state of Alice’s qubit is |1.

      1. When you hardcode alpha = 0.8228 and beta = 0.5683, a call to add_gates gives you an error message. The message is Sum of amplitudes-squared does not equal one. This happens because the value of |0.8228|2 + |0.5683|2 isn’...
