Numerical analyses were conducted on high-harmonic generation from a hydrogen atom driven by quantum light: (1) coherent states, (2) Schrödinger's cat states, (3) Fock states, (4) thermal states, and (5) bright squeezed vacuum states. For light sources (1-3), the results quantitatively agreed with the conventional cutoff. In contrast, light sources (4,5) exhibited harmonics beyond the cutoff proposed in the previous study. Additionally, although the efficiency of harmonic generation dropped sharply beyond the cutoff (21st order) for light sources (1-3), it was found to persist up to approximately the 100th order for light sources (4,5).
