Here's the breakdown:
* No actual quantum particles: The term "quantum" is used to evoke a sense of advanced technology and power, but it doesn't refer to quantum mechanics in the scientific sense.
* Advanced energy weapons: Quantum torpedoes are likely to be incredibly powerful energy weapons, possibly utilizing some form of antimatter or other advanced energy sources.
* Not a single type: The exact nature and workings of quantum torpedoes are never clearly defined in the Star Trek universe, leaving room for variations depending on the era and series.
How to "shoot" them in-game:
* Roleplaying games: Most tabletop RPGs like Star Trek Adventures will have rules for firing torpedoes, often involving dice rolls and considering factors like ship type, crew skills, and the target's defenses.
* Video games: Video games typically implement torpedoes as a specific weapon type, with controls that vary depending on the game. You might fire them with a dedicated button, aim them manually, or even use a targeting system.
Remember: In the Star Trek universe, the exact nature of quantum torpedoes is left somewhat ambiguous for creative storytelling. Don't get bogged down by trying to make them fit strict scientific principles, instead, focus on their power and impact within the fictional context.
