Discussion of how superluminality and superconductivity might be achievable:
Nanotechnology, superluminal signaling, and superconductivity.
http://exoscientist.blogspot.com/2020/03/nanotechnology-superluminal-signaling.html
The first section, the Introduction, is a rather long discussion of why, heuristically, we might suspect superluminality to be possible.
You may want to jump to go directly to the proposals for how to accomplish it in the following sections.
It is notable that at least the superconductivity proposals might be something testable in university undergraduate physics labs.
