Quantum Neural Networks (QNNs)

Definition

Quantum Neural Networks (QNNs) are a type of artificial intelligence model that leverage quantum computing principles to process information. By utilizing quantum bits (qubits) and quantum entanglement, QNNs can potentially outperform classical neural networks in tasks such as pattern recognition, optimization, and complex data analysis. This innovative approach is particularly relevant in fields requiring advanced computation, such as finance, where it can enhance strategies like portfolio optimization.
