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.

Nuclear magnetic resonance

In the Nuclear Magnetic Resonance (NMR) technique, electromagnetic waves are used to control and detect the spin of the nucleus of the atom. You must have heard about the NMR technique being used for spectroscopy and in chemistry as well. In chemistry, it is used to determine the structure of various molecules. In Figure 4.5 you can see the physical apparatus used to build an NMR quantum computer:

Figure 4.5 – An NMR quantum computer

The NMR apparatus consists of a liquid sample containing either carbon, fluorine, nitrogen, or phosphorus, which can be regarded as an ensemble of n-bit quantum computers. The molecules of the liquid emit NMR signals of a frequency of 500 MHz when the magnetic field around them is 11.8 tesla and are commonly mixed in a solvent to prevent inter-molecular interactions. The bore of a large superconducting magnet holds the liquid sample, which is connected to the RF circuit containing amplifiers...
