There’s nothing “special” in the way you imagine about quantum phenomena. They are complicated to describe mathematically because we are limited to a fundamentally imperfect set of symbols, but they are not complicated to obtain the requirements for.

All chemical and light-interaction processes use quantum phenomena if you dig enough into how they work, and it’s especially clear on a smaller scale. If you just make something thin enough, it will start displaying quantum effects, but there is nothing that complicated about “thin”.
