^^If you're talking about extracting energy from the vacuum as a power source, that's a fantasy that violates the law of conservation of energy. At best, you could get a more concentrated amount of energy out of it, but you'd need to put in a greater amount of energy than you could get out.
You're also blurring two different categories. ZPE is a power source; warp is a propulsion system. Just getting zero-point energy doesn't make you go anywhere; it would simply give you the power you needed to fuel whatever drive you did use, whether a warp field, a wormhole, or something different.
However, the Casimir effect does depend on vacuum fluctuations, and has been proposed as a means of producing the negative energy (at least relative to the surrounding space) that's required to create stable warp and wormhole metrics. So the quantum vacuum is being taken into account in multiple cutting-edge FTL theories, including the Cleaver-Obousy warp proposal.
