The tachyon has got a imaginary mass. if it exists, it always have to be faster than the speed of light. It would be also invisible. I belief that they only exist hypothetical in math.
If they exist and you could use them to transport information, it would be possible to teleport matter faster then the speed of light. But that would contain huge problems. Teleportation works with Quantum mechanics. You need to have entangle Quantums on earth and where ever you want. You also need the technology at both places. And the original matter would get destroyed. That would be a huge risk.
The only ways to travel faster than light are:
to eliminate or reverse mass (impossible with normal matter).
find a shorter way than the light is traveling (but you are not faster than the speed of light)
or the easiest way breake the lightspeed. As far as I know the slowest lightspeed is about 61,2 km/hour, 38 miles/hour. (but that wouldn't help either)
