It's a French acronym:
QUorum des Architectes des Nécessités Terribles pour l'Ultime Monde
Translated: Quorum of Architects of Terrible Necessities for the Ultimate World
They're the self-appointed shapers of the ultimate world. "The best of all possible worlds" will be created by this enlightened, cultured elite. They know how to save the world from itself. Sadly, of course, many adherents to the obsolete old world refuse to listen to their betters, so acts termed "atrocities," "terrorism," or "crimes against humanity" by the small-minded will be necessary.
One of the little bits about Ian Fleming's SPECTRE that I always liked is that it was a specifically European (i.e., Continental Europe) organization in its origin and culture. As is QUANTUM. Elitist, highly-"cultured" Europeans, like an evil subset of the Davos Forum attendees. And among other things, they can't abide uncultured thugs like James Bond.
For creativity, and the audacity to actually do it as a French acronym, I declare David the winner, and his prize is winging its way towards him even now.
Stay tuned for future contests around here, as we try to enliven the dark times between Bond movies...
