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.

Variations of this chapter’s code

This book doesn’t cover all the features of Qiskit’s extensive library, but it does cover enough of Qiskit to help you implement some important quantum computing algorithms. To this coverage, we have added some discussion of features that make Qiskit coding easier. Qiskit provides a dozen ways to accomplish any particular task, and this book describes two or three of them.

In the previous section, you learned one way to create and display quantum circuits. In this section, you’ll learn a few more tricks.

Drawing circuits

Consider the following code:

from qiskit import QuantumRegister, \    ClassicalRegister, QuantumCircuit
qReg = QuantumRegister(2, 'q')
qRegNew = QuantumRegister(2, 'qNew')
cReg = ClassicalRegister(2, 'c')
cRegNew = ClassicalRegister(1, 'cNew')
circuit = QuantumCircuit(qReg, qRegNew, cReg, cRegNew)
