Quantum clustering

Definition

Quantum clustering refers to the application of quantum computing techniques to identify and group similar data points within high-dimensional spaces. This method leverages quantum mechanics to enhance traditional clustering algorithms, enabling faster and more efficient data analysis. By utilizing quantum features like superposition and entanglement, quantum clustering can uncover hidden patterns in complex datasets that classical methods may struggle to identify.
