Reporter: I was going
 to ask you to explain
 quantum computing, but...
 [crowd chuckles]
 Um, when do you expect
 Canada's ISIL mission
 to begin again,
 and are we not doing anything
 in the interim
 while we prepare?
Okay, very simply:
normal computers work by...
[crowd laughs, applauds]
No no no,
don't interrupt me.
when you walk out of here,
you will know more--
well no, some of you
will know far less
about quantum computing,
but most of you.
Normal computers work,
either there's power
going through a wire or not:
it's one or a zero.
They're binary systems.
What quantum states
allow for
is much more complex
information to be encoded
into a single bit.
Regular computer bit is
either a one or a zero:
on or off; a quantum state
can be much more complex
than that because, as we know,
things can be both
particle and wave
at the same time,
and the uncertainty around
quantum states allows us
to encode more information into
a much smaller computer.
So that's what's exciting
about quantum computing
and that's where
we're going.
[crowd roars with applause]
Don't get me going on this,
or we'll be here all day.
Trust me.
