Variational Quantum Eigensolver

The Variational Quantum Eigensolver (VQE) is a computational method that uses quantum computers to find the lowest energy state (ground state) of a molecule or material. It combines quantum algorithms with classical optimization: the quantum computer prepares different states and measures their energy, while a classical computer adjusts parameters to find the minimum energy. This approach aims to solve complex quantum problems efficiently, helping scientists understand molecular properties and develop new materials or drugs, by leveraging quantum mechanics' power for more precise and faster calculations than traditional methods.
