ANU puts quantum random numbers online

Re: Are they random or not?

'Either way, randomness by its nature decrees that a previously picked number has the same equal chance of being picked 100 times in a row as 100 different ones being picked once'

Not quite.

More like this:

If we're generating random numbers in the range 1 - n, the chance of the first being a specific number is 1/n, but of being a 'different' number is 1, since we haven't picked any yet.

For the second number, the chance of it being the specific number is 1/n again, but of it being different from the first is (n-1)/n.

And so on (1/n;n-2/n)...

...which doesn't result in an equal chance.

Maybe that should read:

'If a series of numbers fits the definition of random, then a previously picked number has the same chance of being picked 100 times in a row as 100 specific different ones being picked once'

@am I missing something

Not a lot.

They should be able to use one code base, but they have the expense of building and testing on Itanium.
