I don't believe that there is any support for QTVR on the iPad. It seems that Apple is looking towards HTML5 features to provide this type of a VR.
(The Google Earth app for iPad shows how well the iPad would work for VR's when things are there to handle them. Besides the usual single finger pan (all directions) and two finger pinch to zoom, it support two finger pan up/down for tilting to look at terrain, and two finger twist to rotate the view. Very nice.)
