What are the smallest "non-switching" or "non-boolean" properties of quanta, which can we measure?
This is perhaps something of an abstract question but I'm interested in understanding better the role of "switching" in quantum phenomena. Clearly "switching" properties such as a collision or the conversion of an electron into a photon etc. are more easily amplified up to human scale than non-switching properties such as some tiny deviation in the amplitude of a wave.
A switching property is something which has a binary value; yes or no. What I understand less about, is what might constitute a non-switching property of a quanta - perhaps these are velocity and position, or perhaps there is no such thing which we can measure; I don't know -that's what I'm hoping to learn.
The motivation behind this question is the conjecture that it is the ability to construct a "switch" out of some wave activity, which governs the existence and properties of what we call a quanta. But that is just a bit of background. If it helps to understand the motivation behind the question, this reminds me of the process by which a human comes to observe some individual quantum event.
