Quantum Quantity

My theme for the Blogging from A to Z Challenge is contronyms. A contronym is a word with two or more opposite meanings, making it its own antonym. Click here to find out more about these quirky words.
 
Lily with the letter QThe letter Q is often a tough one for many of the A to Z challenge themes, but luckily my list of contronyms has four options. One of the options is quiddity, which was actually the #15tt word the day after contronym was the #15tt word (my first introduction to these weird and wonderful words). How is that for a weird coincidence? But since quiddity is such a rare word, I don’t want to feature it as the contronym of the day.
 
Two of the other Q contronym options are qualified and quite, and like some other words that have been on the list, I think it takes some stretching to really call their definitions opposites. So that leaves me with quantum as today’s featured contronym. I think it’s a solid offering, but since I wrote last year’s Q post on the show Quantum Leap, I do feel a slight sense of déjà vu.

In order to make quantum advances in our understanding of quantum particles, will we end up turning the world into a quantum pile of quantum dust?
