Those are some great choices, even if they are the obvious ones!
University of Maryland (College Park) has a very strong QI program (and hep-ex too, actually) - I have a friend who's considering going there for QI. Colorado Boulder also has a strong reputation in QI (and AMO in general), but I'm not sure about their hep-ex presence. UIUC also recently established a center for QI (IQIST) that got a big cash injection from the university. It just started, so it hasn't had time to build a reputation yet, but given Illinois's reputation in condensed matter I'm sure it will be quite good. Their hep-ex faculty also seem to be pretty good, but there aren't a whole lot of them compared to other schools.
Also, if you need a safety school, UMass Amherst (my undergrad school) has a pretty good hep-ex presence (in particular, our ATLAS group is very good); we have little to nothing for QI though sadly. Not sure if we're too much of a safety, given the other schools you've listed, but it's worth mentioning!
