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 12: Quantum Cryptography – Quantum Key Distribution

A few decades ago, cryptographic techniques were mainly used by governments and military forces to exchange messages during wartime when information was key. Now that huge amounts of data are transmitted over the internet, it has become crucial to design strong cryptographic algorithms to ensure data security and integrity.

To protect your private data, such as banking information and passwords, these algorithms typically use a key to transform it into unreadable scrambled text so that only someone who knows the key can decrypt it and access the information.

Classical cryptographic algorithms rely on the assumption that an attacker only has access to a limited power of computation, but the rise of quantum computing could break this assumption. This has led to the creation of quantum cryptographic techniques that make use of quantum mechanics to encrypt and decrypt data in order to design unhackable algorithms...
