Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I was reading an article the other day regarding measurement and 'Quantum Wierdness' and it made me think about this whole deal with measuring stuff in QM.

[EDIT: Article: http://www.anu.edu.au/news/all-news/experiment-confirms-quantum-theory-weirdness ]

The thing is I regularly work with what's called SEE (Single Effect Events, sometimes also Single Effect Upsets) in my work. This is bit errors, transistor upsets and damage resulting from high energy electrons and protons in outer space (on the ISS).

Now this can all be dealt with quite classically. Measurements have been made of the particle flux and energy distribution, and then you simply have to design your electronics to be safe, should an SEE occur, or protect your electronics with shielding.

However, I was thinking about this whole thing from a QM perspective today, since these electrons and protons should be quantum particles, right? I guess the SEE could be seen as a "measurement" of some sort? The thing is the word "measurement" confuses a bit. It leads one toward ideas of experiments and setting up a system to measure some effect, but here it just 'happens' with some statistical probability.

But how far from the "knowledge" of such an event can we remove ourselves? I mean this in the sense that, what if on the Integrated Circuit, a portion of transistors are running some kind of logic, but with no connections to any interface we are looking at, or perhaps even capable of looking at. Would we still say that, even though we can't 'measure it', these SEE's are happening, meaning that the quantum particle (electron or proton) interacts with the transistor. If this is the case, the 'oberserver effect' is then non-existant.

This is in the direction of "is there a sound when a tree falls in a forest, but no one is there to observe it".

Could anyone with some more expertise perhaps shine a little light on my thoughts and tell me if this trail of thought leads to despair down the line.

Is the cake a lie?

Thanks in advance :)
