21.1 Introduction

The circuit model of quantum computation (1–3) has been a powerful tool for the development of quantum computation, acting as both a framework for theoretical investigations and a guide for experiment. In the circuit model (also called the network model), unitary operations are represented by a network of elementary quantum gates such as the CNOT gate and single‐qubit rotations. Many proposals for implementing quantum computation have been designed ...
