I don't think that (yet) there exists computers that are completely 
based on quantum components. Maybe they have a quantum based arithmetic
unit but the other components are certainly conventional. I don't know
what kind of OS is used on such machines. But I wouldn't be surprised 
if it is some kind of BSD or Linux (maybe Gentum-OS). ;-)

I'm really not an expert on quantum physics but I don't think that a 
quantum computer could be dangerous. :-)

In fact, "a quantum is the minimum amount of any physical entity 
involved in an interaction" (wikipedia). 

I could imagine that a single high energy gamma quantum (that can have 
a energy of some MeV) could maybe destroy a flash memory cell or a DNA 
molecule. But such high energetic photons are not used in quantum 
computers. Quantum does there only means that they are using very small
entities which can be described by the theories of quantum mechanic, 
like electron spins or quantum entangled photons.

And of course there doesn't exist particles that are moving faster than
light (at least no such particle is ever be detected and AFAIK there 
are absolutely no indications that such particles exits). You probably
mean "quantum teleportation". But this has nothing to to with the 
movement of particles. It is a phenomenon that results from the quantum
entanglement of e.g. two electrons and has to do with the nonlocality
of such phenomenons. When you measure the quantum attributes of one of 
these two electrons you instantaneous influence the quantum attributes 
of the other one, regardless of its distance. But if you wanna know the
quantum attributes of the second electron you need the information 
about the measurement of the first one. And because you cannot transmit
this information faster than light you also cannot use "quantum 
teleportation" to really transmit information faster than light.

My English as well as my knowledge about quantum physics is not 
sufficient to explain it better. But you can find many information about
the strange and also fascination aspects of quantum mechanics in the
internet. Just look at wikipedia.
