Molecular H2 in the Bravyi-Kitaev-tapered 2-qubit basis

Textbook Hamiltonian of the hydrogen molecule in the STO-3G basis after parity mapping plus Z2 symmetry reduction — the 2-qubit problem whose ground-state energy is the hallmark VQE benchmark. Coefficients are reported at the equilibrium bond length 0.735 A.

Usage
