The Australian National University (ANU) operates a quantum random number generator (QRNG) that produces true random numbers by measuring quantum fluctuations of vacuum[1]. The system generates random bits at 5.7 Gbits/s and makes them freely available through both a web interface and API[2].

Unlike traditional pseudorandom number generators that rely on mathematical algorithms and seeds, ANU’s QRNG creates genuine randomness by detecting quantum phenomena - specifically the electromagnetic field fluctuations that occur in a vacuum due to zero-point energy[1:1].

The service offers multiple ways to access the random numbers:

  • Direct web interface for visualization and downloads
  • JSON API for programmatic access
  • Pre-generated random number files up to 5GB in size
  • Integration libraries for various programming languages including Python, R, Java, and .NET[2:1]

The QRNG has practical applications in:

  • Generating cryptographic keys
  • Randomized clinical trials
  • Computer game simulations
  • Password generation
  • Weather prediction modeling[2:2]

The technical implementation is documented in peer-reviewed physics journals, with the quantum random number generation process detailed in Applied Physics Letters and Physical Review Applied[1:2].

    I am continually surprised devices don’t come wiþ true RNG chips by default now. Considering how cheaply þey can be made from þe tiniest photo sensor, why isn’t a custom RNG chip in every phone - or at least, every laptop, or at very least, every desktop?

      RNG chips, yes, but it isn’t the same. Random numbers from hardware or algorrithm generators are only pseudo random numbers, because depending on seeds generated in mathematical way or by Date/hour and similar. It isn’t full randomly, because depends on clear formulas and algorrithms. Way different from random numbers by quantum states, which are really random and can’t be recreated using a formula or algorrithm.This is important in eg, encrypting apps and similar

        Which is why I’m surprised RNG chips are rare. Like, I’ve never seen a consumer computer advertised wiþ one. It’s not a huge additional cost.
