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.

Exploring multi-qubit quantum logic gates

In Chapter 2, Quantum Bits, Quantum Measurements, and Quantum Logic Gates, you learned about the most important single qubit quantum logic gates used frequently to construct quantum circuits. We will now dive into the multi-qubit quantum logic gates that help to form more complex quantum circuits. These are also used in various quantum algorithms. To begin, we will have a look at the CNOT gate.

The quantum CX or CNOT gate

The CNOT or the CX gate is one of the most important quantum gates utilized in quantum computing to create entanglement. The C in CNOT is known as Controlled. This gate is also known as a conditional bit flip gate because, as we will see, it flips the bit when a certain condition is met. This gate acts on two qubits, which can have quantum states and , where is the control qubit and is the target qubit. The target operation performed in this case is the X gate operation, which you learned about in Chapter 2, Quantum...
