'Blind' Quantum Computing Proposed For the Cloud

Quantum computing is just a rather basic branch of computer science which seems to be winning all the hype in the world at the moment because there's not much sexy in terms of hard non-biological research with a practical slant.

I'm not quite sure how the output remains unknown to the computer. I know most cloud services either haven't or won't last long enough to give you all the output you were expecting to get for free/absurdly low cost, but I'd be very impressed with a computing system which is able to deliver you something without knowing it's delivered it.

Of course, there are various computations which can be performed partly by a separate processor without the initial input and final output being known by that separate processor, but there's nothing quantum-y about that.
