Quan vs Kitana is not a good match-up for Quan. If your reasoning for Quan being good for Kitana is:
They have equal zoning: You're not playing a Kitana who can consistently iaf
Their footsies are similar: Quan has a stubby d3 and a non-existent d1. Kitana's strings reach 1/4 to full screen, are safe on block and 21 is decently fast and easily hit confirmed. Quan has a string that reaches about 1/4 screen, but it's very slow and extremely punishable between each motion.
Cutter: LBSH, if a Kitana ends more strings with cutter than ending it as 21 or 212, you're not versing a Kitana
Rune Trap: Although very good, 1 bar 50%+ > 3 bar 50%+
