Potential Energy Curve: H2 Molecule
VQE finds the ground state energy of the hydrogen molecule (H2) at each bond length.
The minimum of the curve gives the equilibrium bond length (~0.74 Angstrom) and bond dissociation energy.
This is the canonical near-term quantum computing application: simulating molecular electronic structure.
