The Variational Quantum Eigensolver (VQE) is a hybrid algorithm combining quantum computers with classical optimization. It finds the ground state energy of molecules—crucial for drug discovery, materials science, and chemistry simulations.
⚡ The Hybrid Approach
VQE uses quantum hardware to prepare trial states and measure energies, while classical computers optimize parameters. This division plays to each platform's strengths, making VQE ideal for near-term quantum devices.
Quantum Part
Prepare parameterized states and measure expected energy values
Classical Part
