Vector Database For Quantum Computing

Definition and Core Concepts of Vector Databases for Quantum Computing

A vector database is a specialized data management system designed to store, index, and retrieve high-dimensional vectors efficiently. In the context of quantum computing, these vectors often represent complex data points, such as quantum states, entangled particles, or results from quantum algorithms.
