When Schrodinger found out and pointed out
in 1935 was that you have a complete knowledge
of the whole without knowing the state of
any one part. That a thing can be in a definite
state, even though its parts were not. That
idea was, was never properly explained. And
people don't understand it except quantum
physicists. It's not a complicated idea but
it's an idea that nobody would ever think
of. From the human experience that we all
have and that is that a completely perfectly,
orderly whole can have disorderly parts. Quantum
information is like the information in a dream.
If you start even trying to share it with
one person besides yourself and talking about
it, you start forgetting the dream and only
remember what you said about it. Can you understand
what a quantum computer can do differently,
without understanding about physics. Yes,
because just as Shannon and Turing in the
mid-twentieth century separated the idea of
computing and information processing from
the theory of electrical circuits. Or the
way gears interlaced in an old fashioned marchant calculator.
So the theory of quantum computing seperates
the essential information processing part.
Treating it as quantum, it doesn't matter
what kind of quantum system you use to do it
Somebody asked Faraday, what the value
of this new chemical that they discovered was
And Faraday said that scientists are
always having to answer the questions of people
where as soon as they hear about something
new they ask well what are you going to use
it for. And Faraday says I can do no better
that to give the answer to that question that
Franklin always gave when someone asked that
question. Which is what's the use of a baby.
The 
thing is quantum information processing is
so different from what we have thought information
processing is like for the last 60 years.
That it would be a shame not to explore it
and find out what we can do with it.
