When creationists talk about origins, they generally don't mean

is, the act of creation is a free act. And so by the concept of
freedom, I come to the bomb-testing experiment, which experiment
clearly demonstrates freedom abounds.

So I was thinking how to simulate the bomb-testing experiment on a
regular computer. The experiment has already been done on a special
light based computer.
The experiment has been done using real photons which 1) either travel
on both paths simultaneously and then constructively or destructively
interfere to determine which end detector will be hit; or 2) travel
only one of the two paths if there's a working photon detector (bomb)
located on one path. The presence of the working detector on the
'bomb' therefore has an impact on the behavior exhibited by the
photon.
I wouldn't characterize that experimental arrangement as a "light-
based computer."
First of one would need some free input, and since the random function
generally works partly or in whole from registers, one would need to
make another randomfunction based on things like noise signal from a
sound or video card etc.
Secondly the role of the silvermirror IMO is passive. So to say
nothing get's to be decided at the silvermirror, but the silvermirror
just represents an ultra-sensitivity to variable courses of action.
It's at the first half-silvered mirror that the photon in case 2) is
either sent on the upper or the lower path. And it's at the second
mirror that the interference in case 1) takes place and determines
which of the two end detectors will 'see' the photon.
the decision is made at the point of origin, in relation to the
endpoint, and the silvermirrors just represent ultrasensitivity giving
radically different results for slight variations in trajectory
chosen.
But the point of origin can be removed by an arbitrary distance from
the rest of the bomb-detector. If the photons come from far enough
away they may well originate long before the bomb detector is even
constructed or any bomb (with either a working or non-working
detector) is placed on one of the possible paths.
