USS Voyager being hit by quantum resonance charges
Quantum resonance charges were a type of weapon employed by the Pralor and their Automated Personnel Units.
In 2372, a Pralor vessel attacked the USS Voyager, in an attempt to dissuade the Voyager crew from attempting to retrieve Lieutenant Torres, whom the Pralor had kidnapped. The attack rapidly breached Voyager's shields, forcing them to retreat and develop a new rescue plan. (VOY: "Prototype")
