Quantum information is actually different from classical information (classical entropy). Quantum information is (believed to be?) a conserved quantity; classical is not (it never decreases). A quantum random number generator is just emitting quantum bits: without having had those qubits in the first place, you can't have computed them ahead-of-time, so they're random.
