Unfortunately, the only physical system in which anything approaching topological protection has been seen is a two-dimensional particle gas experiencing the fractional quantum Hall effect. That effect requires formidable extremes of low temper ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
