I just don't get why you would want to use a quantum computer to generate random numbers. Hardware-RNGs are cheap and have existed for decades. Your CPU probably has one built-in. Some even rely on quantum effects such as shot noise, but where is the advantage over using say thermal noise of a resistor? Both are completely unpredictable.

If you want random numbers just for yourself, all of the approaches you mention are fine to use. The difference is that by using a quantum computer, one could generate random numbers and convince others that the numbers are actually random and not rigged.
