Using the “drums” as speakers is an interesting idea, but unfortunately the drums’ can only be entangled in a near-perfect vacuum. With no air present to transmit sound waves, they won’t make very good speakers.

You can find the paper for free on the arXiv here. All of the coolest quantum information papers are on the arXiv!

This is a great idea! We hope that more organizations will make public random sources that are compatible with NIST’s Randomness Beacon. You can add (or “XOR”) their outputs together, which will increase trust that the sum is more random and trustworthy than any single source.

@Daniel, you are absolutely correct! There is a very small probability that unentangled particles or even a deterministic source could produce data like the data we observed in our experiment. This is why we write in our paper that our 1024 random bits are uniformly distributed “to within 10^{-12}”. This error…

Stephan, NIST’s 1024 random bits ARE the digits in a halting probability, but I can’t tell you which one. ;)

@RonDunE, I worked on this research, so I am excited to see commenters here taking an interest! Our random numbers do pass tests like Kolmogorov-Smirnovor and Diehard. However those tests cannot distinguish between a genuinely unpredictable random string or a completely predictable string whose digits appear to have a…
