Still a 32% -> 56% jump in equity because of a Qx seems kinda high? Just for having a high card Q?

Your equity went from 69% on the flop to 56% on the turn, it didn't go up. And it isn't just queen high he could have, he could be playing any two cards.

There are a total of 1326 possible preflop hand combinatons. If he has K,9,7,4, any pocket pair, AQ, or AJ he is beating you so lets figure out how many combinations of those hands there are:

pocket pairs: 60 (taking into account the fact that there are only 3 A,K,T,9,7 and 4s left)

two pair(K9, 74 etc): 108

one pair(Kx 9X etc): 408

in total there are 576 hand that you are behind on the turn. That means that with Ace high you are ahead against 56.6% of all hands you opponent could be holding.

EDIT: If someone could check my math that would be great
