If I read the data stream by light leakage off of a fiber with a photodiode, it would not change the quantum data one bit. This is horse pucky.

Not at the level this stuff operates.

We're talking stuff kind of on the order of individual photons of light type stuff. You read it, it's gone.

At the quantum level, merely measuring something affects it. You may have heard it said that you can know the location, but not the velocity, or the velocity but not the location?
See my tag line and look it up. It is all probabilities until a measurement is made.
