Part 2 Fundamental algorithms and patterns
With a solid grasp of quantum states and operations, you’re ready to implement and apply fundamental quantum algorithms and computing patterns. These aren’t just theoretical constructs—they’re the building blocks used in real quantum applications, including search and optimization problems.
Chapter 5 introduces quantum oracles and their role in algorithm design. Chapter 6 shows how oracles enable Grover’s search algorithm, a quantum approach that quadratically speeds up unstructured search problems. Chapter 7 develops your understanding of the quantum Fourier transform, and Chapter 8 puts it to work in various applications. Chapter 9 brings these concepts together with quantum phase estimation and quantum counting, completing your toolkit of fundamental quantum algorithms.
