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.

Functions and iterations in Silq

Functions are blocks of reusable code that are organized in a way such that it brings modularity to your code and makes your code clear and legible to read. Just as with any other programming language, Silq offers some built-in functions to use and lets us define our custom functions according to our requirements. For example, you have already seen H() in the preceding code blocks, which is a Hadamard function and a built-in function.

Iterations in computer programming are the repeated execution of code statements until they meet a certain condition. These are also known as loops in computer programming. Silq offers two different kinds of iteration statements, namely while and for loops.

Let's now see some example code where iterations are being implemented inside a function. Please note that to run Silq programs, it is important that you always define a function called main() and then execute your code inside that function. You can create...
