I kind of think of like, Schrödinger's cat, 
but the the cats inside a computer
I guess it kind of sounds like something from a
James Bond film,
like something with a lot of ice
Computing, like software design or
something like that?
Umm, is it
kinda like
quantum physics in space, but in a computer?
it's to the number of atoms to the power of 2
I've just googled it, so..
according to Wikipedia, quantum computing is a
quantum mechanical phenomenon
so ahhh
yeah, I know everything now.
Okay, let me have a go at it.
A quantum computer is a machine that processes quantum information.
So what is quantum information? 
So imagine we have particles
like electrons or photons or atoms, even
tiny superconducting circuits
they behave quantum mechanically, which means
in contrast to the way a normal computer
would store information, which is through a bit
which can be 0 or 1
these objects actually can be 0 and 1 at the same time.
now AND is not a very good descriptor, but it'll do for now.
When we have many
of these qubits we are essentially
describing binary strings existing in a
way all at once.
and these are in these complicated entangled states
so when a quantum computer computes and runs an algorithm
it's actually manipulating the
interactions between these quantum objects,
between the qubits
in such a way
that the probability of measuring a
particular binary string at the end of
the calculation is amplified to be
that which is the answer to your problem.
Now if all of that is a little bit spooky
don't worry, anybody who claims to
understand quantum mechanics
actually hasn't understood the first thing about it.
