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.

Ion-trap quantum computers

Ion-trap-based quantum computers are completely dependent on electron spins and through these spins are able to represent the qubits. Atomic spins are very subtle in nature and difficult to observe, due to which they are also difficult to control too. Therefore, to have control over these particles, it is necessary to isolate them from the environment. This process is done by trapping a minimal number of atoms with the help of an electromagnetic field, and immediately cooling them so that they lose their kinetic energy. As soon as this process is completed the atomic spin can be controlled to construct qubits. Figure 4.4 shows the ion-trap-based quantum computer:

Figure 4.4 – Trapped ions

From Figure 4.4, we can observe that the ions are trapped between the cylindrical electrodes and this apparatus is usually kept in a high-vacuum container. The arrows shown are modulated laser light beams, which are placed incident to the...
