10.1 Building and training a quantum neural network

Just like quantum support vector machines, quantum neural networks are what we called ”CQ models” back in Chapter 8, What is Quantum Machine Learning?, — models with purely classical inputs and outputs that use quantum computing at some stage. However, unlike QSVMs, quantum neural networks are not a ”particular case” of any classical model, although their behavior is inspired by that of classical neural networks. What is more, as we will soon see, quantum neural networks are ”purely quantum” models, in the sense that their execution will only require classical computing for the preparation of circuits and the statistical analysis of measurements. Nevertheless, just like QSVMs, quantum neural networks will depend on classical parameters that will be optimized classically.
