From a mechanical perspective, no, since they're differing systems. If you wanted it to apply I'd consider accounting for it in the cost of Non Iconographic and Dyslexia since they respectively shifted in their impact in the game though.
Realistically I'd argue that there's some fundamental difference between language and symbols because one could argue the same for the English alphabet or entire words, as they are just abstract symbols.
One might say that the iconographic nature of languages like Chinese might mean you can't tell what the Kanji/etc meant (i.e. that certain words were created to visually represent those concepts), which might give penalties for using it broken/understanding difficult or new words as you can no longer intuit meaning by the symbols themselves, but not really impact the abstract language portions.
To a degree, yes. As was mentioned elsewhere there is a thing called Wave Function Collapse, which occurs when a measurement is taken of a quantum system and forces the system from superposition (multiple states at once) into a single state. A measurement could be seeing it, scanning it, bumping into it, etc (not human conscious observation, that's an old and weird interpretation and not relevant nowadays).
Before (and after as well) you actually collapse the wave function you can perform meaningful math using the quantum particles. The one way I'm familiar with is for computer calculations, which is what quantum computers are aiming for. This is basically done by canceling out certain possibilities to only allow the wave function to collapse into ways that give meaningful mathematic results.
As such, this is barely relatable to a quantum Santa which uses this nature to perform meaningful present sharing actions simultaneously using quantum superposition of a quantum system that is spread out over a very large area. Of course, basic quantum mechanics becomes statistically the same as normal physics (i.e. 10 quadrillion particles average out to one normal human), so Santa would need to be a reality bender to allow for such small chances to occur to allow a human sized being to affect a huge area... but whatever.
