First of all, I personally couldn't care less about rankings; however, a future employer might. For my PhD I am thinking of applying to schools with groups in silicon quantum computing, and the two places whose research I have read a lot about are Princeton (Petta) and UNSW (Morello, Simmons, Dzurak), and others. Assuming I could even get into Princeton, and that the quality of my PhD research are the same at both places, how will the name recognition of these two schools affect my future employment, either in academia or industry? Any other pros/cons?
As usual, no simple answer ... it depends on a host of other factors. I can't speak for academia; my career has been entirely in industry and patent law.
(a) Do you plan to continue a career focussed in the niche field of your PhD work?
(b) What country do you plan to work in after your PhD (US, Australia, elsewhere)?
I wouldn't be fixated so much on rankings
per se. The key factors (beyond your personal competencies, that is) are reputation and brand-name recognition: of the advisor, of the department, and of the school. If you plan on staying in your niche field, then the reputation and brand-name recognition of your advisor is of primary importance: If you have a well-established advisor, someone interviewing you for a position in your niche field will have an initial favorable impression regardless of the overall reputation and brand-name recognition of the department and school.
But regardless of your initial career plans, life doesn't always work out that way. The more you stray away from your niche field, then the reputation and the brand-name recognition of the department and of the school come more into play. In the absence of more specific knowledge, people tend to have subjective, gut initial impressions based on the department and school. A strong favorable impression will at least help get your foot in the door for consideration, and that step is often the hardest when it comes to transitioning to a different field. The rest is then up to you personally, of course.
Reputation and brand-name recognition, of course, depend on the country in which you apply for a position, the field of work ... and on the hiring managers (which countries did they come from? which schools did they go to?).
