Quantum Computing with Silq Programming

By: Srinjoy Ganguly, Thomas Cambier

Overview of this book

Quantum computing is a growing field, with many research projects focusing on programming quantum computers in the most efficient way possible. One of the biggest challenges faced with existing languages is that they work on low-level circuit model details and are not able to represent quantum programs accurately. Developed by researchers at ETH Zurich after analyzing languages including Q# and Qiskit, Silq is a high-level programming language that can be viewed as the C++ of quantum computers! Quantum Computing with Silq Programming helps you explore Silq and its intuitive and simple syntax to enable you to describe complex tasks with less code. This book will help you get to grips with the constructs of the Silq and show you how to write quantum programs with it. You’ll learn how to use Silq to program quantum algorithms to solve existing and complex tasks. Using quantum algorithms, you’ll also gain practical experience in useful applications such as quantum error correction, cryptography, and quantum machine learning. Finally, you’ll discover how to optimize the programming of quantum computers with the simple Silq. By the end of this Silq book, you’ll have mastered the features of Silq and be able to build efficient quantum applications independently.

Chapter 9: Quantum Algorithms II – Grover's Search Algorithm and Simon's Algorithm

In the classical computing system, the problem of searching for an element in a particular database or array is a significant one. The complexity of searching for an element in an unstructured database in the classical computing case leads to taking time. However, in the case of quantum computing, the complexity of searching for an element in an unstructured database can be done in less time than that of the classical case.

In this chapter, you will dive into Grover's search algorithm, which is primarily an algorithm to search for elements in an unstructured database with a search speed better than that of classical search. We will cover the following topics:

  • Introducing search algorithms
  • Getting started with Grover's search algorithm
  • Grover's search for one solution using Silq programming
  • Grover's search for multiple solutions using Silq programming...
