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 single quantum bits – qubits and superposition of qubits

In Chapter 1, Essential Mathematics and Algorithmic Thinking, in the Vectors section, you learned about the mathematical representations of qubits and we observed that vectors make the computations to be performed onto these qubits a lot easier. In this chapter, you are going to dive deeper into the notion of qubits, not only from a mathematical perspective, and gain a deep understanding of them. This will help you in the next chapter when you program qubits. The qubit is the most fundamental unit of quantum computation and information and can be thought of as the quantum equivalent of a classical bit, which is binary in nature. Classical bits can only be in the states of 0 or 1, which represent the two voltage levels on and off respectively. This means that classical bits can be only present in either of these two states – 0 or 1 – at any one time. However, qubits can be in a state that is neither...
