A RNG with 10^118 secure bits isn't really that great at all. All I need is a 49 character entirely random password or a 36 word long xkcd-936 complaint password. I can then use them as my key/seed for secure cryptosystem (RSA or Rabin's) and then generate on the order of 10^118 bits before my system is breakable. QRNG's are only useful when you need large amounts of random data are needed for a (relatively) slow device. The average person has little need of a QRNG. That said, the work itself is an interesting method to create one, its just that the article makes it sound like something its not.
(I'm not a cryptologist, so feel free to correct me.)
