Idea for light speed or possibly faster than light speed travel?

So the other day while I was folding up some laundry I had this idea pop into my head. Now I'm not an expert or anything and I dropped out of physics in highschool, but I do think quantum physics are interesting like most people. I figure this would probably be the best place to post this due to the nature of blackholes. So this is really more of "hey is this possible in theory?" kind of thread.

So here is my idea:

A vessel of some sort could travel at potentially faster than light speeds by persistantly creating and destroying a black hole infront of the said vessel. This would use anti-matter particles to destroy the black hole, and "transporter" technology to allocate dense mass in the space infront of the craft. By constantly creating and destroying blackholes infront of the vessel, would it not be possible to constantly accelerate into the blackhole, and then destroy it and make a new one further away? This process would have to be repeated many many times in a second, and the vessel would be close to the point of mass, or in otherwords, inside the black hole. This brings up all sorts of questions about time travel too but Im not going to touch on that. :P

My idea comes from the knowledge that black holes are incredibly dense, small peices of mass that have so much gravity it actually bends and "sucks in" light and space time. Now I have two questions that are related to my idea: Is it true we can transport matter through energy to a limited degree? I remember something about someone transporting an apple or a vegetable through this method, and it came out on the other end a pile of mush. Also, I know doctors can use lasers to move entire cells around in a petre dish.

Anti-matter has been proven to exist now hasn't it? Of course it's a whole mystery in itself on how to actually store and create large amounts of it, but I think thats worthy of its own topic. Also, I assume anti-matter would be able to efficiently destroy a blackhole. Would it be able to in theory? What else could?

Anti-matter would increase the mass of the black hole, not distroy it. I don't see any way that quantum teleportation could be useful here, if that's what you meant. There is however a similar and simpler idea called the Alcubierre warp drive. Unfortunately it requires that we are able to produce large quanties and control a type of matter that has never been detected. Even if such matter exists, it would almost certainly be absurdly difficult to produce it and control it, and even if we could, it would be disappointing. Nothing at all like Star Trek.

No. What we can do is to transport the quantum state of a single photon. What that process does is essentially to change the polarization of a photon that's already at the "destination" to what was previously the polarization state of a photon at the point of "departure".

Yes, in 1932. (That's when the positron was discovered).

As I said above, it can't. I don't think anything can, except time. Just wait much longer than the current age of the universe, and it will destroy itself by emitting Hawking radiation until it's gone (or whatever happens when only a really tiny piece is left...no one really knows).
