The quantum torpedo was a tactical quantum weapon deployed aboard starships that utilized a plasma warhead. Quantum torpedoes were used by several galactic powers including the United Federation of Planets, and the Cardassian Union. The quantum warhead relies on rapid energy extraction from zero-point vacuum. This is established from an 11-dimensional space-time membrane, twisted into a Genus-1 topology string, housed inside the ultraclean vacuum of a 1.38 meter-long teardrop shaped zero-point field reaction chamber. The detonation of a photon torpedo warhead, enriched with fluoronetic vapor, inside the torpedo powers a continuum distortion emitter. It expands the membrane and pinches it out of the background vacuum. The membrane forms into subatomic particles accompanied by a high-explosive energy release of two hundred isotons.
