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.

Introducing classical cryptography techniques

From the earliest algorithms that are easily hackable to the recent ones that rely on hard-to-solve mathematical problems, cryptographic techniques have evolved over the decades to become stronger against attacks.

In this section, we will look at how cryptography works in classical computation. This will serve as an introduction to quantum cryptography in the next section.

Let's begin by introducing the basics and the vocabulary of classical cryptography.

The basics of cryptography

First things first, what is cryptography and why is it needed? Suppose you want to send a secret message to someone. If you do not possess a secure communication channel with this person, whether physical or virtual, then whatever means of communication you use, your message has a chance of being intercepted by a third party. This third party, also called an adversary, eavesdropper, or Eve, may take various forms and interfere at any point of...
