You can use "itself" only if this "it" can be in multiple
locations and heading in different directions.
That is a property of waves. But you will only ever observe a
single photon from this wave.....
Waves/Photons, doesn't matter what you call them.
Within the quantum computer this wave/photon is simultaneously in many
different locations/doing many different things, performing
computations and doing useful work using all of its separate
superposed instances of itself. Once it's done doing all this work it
settles down on a final value which we can read. And it will be
correct, and may have finished an enormous computation in a short
period of time, if and only if, it did in fact split up and do all
these independent things simultaneously.
Or you can view the action of a quantum computer as a simple
interference effect. Incorrect solutions to the algorithm destructively
interfere. You don't have to introduce ideas such as 'being in different
locations and doing different things.' It is just simple interference in
a wave. (And it is all in one world, because interference can only occur
within the one world.)
On that we agree. But where did those other photons come from?
How did they get to be in different positions going in different
directions?
They aren't.
How do do you explain the experiment with beam splitters and
recombining light at a half silvered mirror to interfere and only be
reflected one way?
Photons have both wave-like and particle-like properties. That is
quantum physics.
So do you accept or reject that this "wave" can be in different places
simultaneously?
A wave is not a localized object, so the same wave can extend to
different locations.
