I don't think he has any idea what they mean beyond "sciencey stuff."

Looking at an impossibly advanced aircraft and assuming it's based on "extreme advances in quantum mechanics and nuclear science" makes as much sense as saying it's based on "extreme advances in organic chemistry and software design." No one with any grasp of engineering would jump straight to these fields that are not, so far as we know, associated in any way with aerospace propulsion. He's just grabbing the coolest science buzzwords he knows to make himself sound serious and professional.
