Truly random

Gerhard Richter painted a series of pieces that includes swatches of apparently random colors. However, any process developed by the human mind is likely to be non-random as the human brain is particularly bad at either generating or recognizing truly random sequences. Even most computer generated sequences are only pseudo-random. This piece “Random Richter 1” is generated by one of the few truly random processes in nature–that of quantum mechanical noise. The physics behind the experimental apparatus that generates the random colors is described in the paper here. You can generate your own random sequences from the experimental implementation of this protocol via the ANU Quantum Random Numbers Server. Here is the first in the series of “Random Richters”.
