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.

Criteria for quantum computation existence

In this section, we will be looking at the conditions which are necessary for making quantum computing a reality. All the current quantum computers are affected by quantum noise, which is also known as decoherence. Decoherence creates loss of quantum information and is therefore considered as a type of noise, and happens when the qubits interact with the environment over a long duration of time. A high accuracy of the computations performed by quantum computers is achieved when there is less interaction of qubits with the environment. Decoherence destroys the unitary operations that are a very important aspect of quantum computation, as we discussed in Chapter 1, Essential Mathematics and Algorithmic Thinking.

There are primarily four conditions that are required to make quantum computing happen. They are as follows:

  • Quantum information depiction
  • Unitary transformation capability
  • Making the reference initial quantum states...
