A digital simulation framework decomposes quartic vibrational Hamiltonians into Bogoliubov-diagonalizable fragments, enabling Trotterized dynamics and eigenenergies on bosonic quantum hardware, demonstrated on a double-well model and small molecules.
This has the effect of changing the cubic and quartic co- efficients in the Hamiltonian as cj → cj − ck j , while also modifying the linear, quadratic and constant terms
