  Re: different - probably much less expensive - approaches to RNG;

  From "Cloudflare: New source of randomness just dropped" (2005) https://news.ycombinator.com/item?id=43321797 :

  > Another source of random entropy better than a wall of lava lamps:

  >>> "100-Gbit/s Integrated Quantum Random Number Generator Based on Vacuum Fluctuations" https://link.aps.org/doi/10.1103/PRXQuantum.4.010330

  100Gbit/s is faster than qualifying noise from a 56 qubit quantum computer?

  There's yet no USB or optical interconnect RNG based on quantum vacuum fluctuations, though.
