I attended a Google talk where they acknowledged difficulty in controlling their device. That was given as the motivation for running problems that consist of "random gates".

My understanding from reading Scott Aaronson's FAQ is that the "random" in "random gates" just means that they pick a random circuit to evaluate. But this circuit is known, just like a program can pick a random number and then print it out.

The fact that quantum computing behaves "randomly" by nature further complicates the discussion :)
