That's a not a definition. Just another fuzzy word to say subjective experience.

One's state of consciousness is very much their subjective experience while conscious

Yes. But qualia, subjective experience, state of consciousness, phenomenal consciousness, etc. these are not good definitions (as asked by OP). These are just all talking about the same thing without a proper definition that would allow us to define its different states. Measure, quantify, understand, sort, etc etc.
