How can I hide empty Quick Tab item when there is no content in it?
I already checked it. But still the 'View' I assigned to that quicktab renders some div's which I posted in my question. By the way, I found the solution, you just need to add the filter in that particular view. Suppose view of content type 'movies' then add a filter "content:movies => not empty (IS NOT NULL)". That's it.  Hope this help others too.
