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.

  1. What’s the output of the following circuit?
  1. Try to find values of a subscript 0 , a subscript 1 , b subscript 0 , and b subscript 1 satisfying . (It can’t be done because the two qubits in question are entangled.)
  2. Show that the circuit in Figure 4.22 creates the state by writing the circuit’s matrix representation and calculating the circuit’s output.
  3. Modify the code in this chapter’s Working with Qiskit section so that the resulting state is . Output a multi-qubit sphere like the one shown in Figure 4.18.
  4. Between 1983 and 1993, there were approximately 105 boys born in the US for every 100 US-born girls. Given this ratio, what’s the probability that a family of three would have exactly two girls and one boy (in no particular order)?
  5. In this chapter’s What would happen if there were hidden variables? section, we conclude that the overall probability of measurement disagreement is at least 5 over 9. We say at least because this...
