Quantum convolutional neural networks (QCNNs) are a class of quantum machine learning models that extend traditional convolutional neural networks by incorporating quantum computing principles. These networks utilize quantum bits (qubits) and quantum gates to process data in ways that classical networks cannot, enabling them to learn patterns and features from quantum data more efficiently. QCNNs can be particularly powerful for tasks involving high-dimensional data, such as image and signal processing, where they can potentially achieve superior performance compared to their classical counterparts.
congrats on reading the definition of quantum convolutional neural networks. now let's actually learn it.
