The blade of a Quantum Saber is not made of plasma like traditional lightsabers. Instead, it is harnessed power of a contained quantum singularlity, producing a blade that cuts through materials at the atomic level. This weapon is exceptionally effective against lightsaber resistant materials, and can parry lightsaber blades. The longer the blade is active the weaker the singularity becomes, reducing the strength of the cutting power to that of a standard lightsaber blade.

This lightsaber has been treated with Sith Alchemy, rendering the weapon almost indestructible and completely resistant to lightsaber attacks.

This lightsaber is equipped with a specialized emitter that renders the blade silent during normal operation, but still makes noise when it comes in contact with another blade, energy, or solid matter.
