Oh, no, wait! That's not right, either...
How To Be... a Quantum Mechanic
Okay, so there's really no such thing as a "quantum mechanic." Yet.
However, with quantum communication on the horizon (possibly closer than you think), and quantum computers in development (the first one has already been built), and the possibility of all of this leading to artificial intelligence and robots and warp drive (also in development and has been done on a small scale), I can't think of a better name for the guy that has to come around and fix your tech when it breaks down. I imagine, at first, at least, that this will take a lot more schooling than a trade school.
My advice? Take as much quantum physics as you can. The next generation of technology is coming. It can't hurt to be prepared.
