Random number generators are readily available online
for extremely cheap, but do they produce truly random
numbers? The purpose of this research was to explore
randomness and ways to test for it, to build the simplest
quantum random number generator (QRnG) given the
resources at hand, and prove its intrinsic randomness using
a logical and mathematical analysis. The components of the
experiment were radioactive compounds [Ba – 133, Co – 60,
Ra – 226], Geiger Tube, and a ST – 360 Radiation Counter.
By collecting one batch of decay counts as a result of gamma
ray detection from each of the radioactive compounds,
respectively, the average of the decay values was used to
assemble a logic gate. This logic gate was constructed such
that when the decay count was greater than the average, a
value of 1 was given, below the average, 0. This yielded a
binary sequence that, according to the principles of nuclear
and quantum physics, should be perfectly random. Using
the defined process, three separate strands of sixty perfectly
random binary values were attained. Using a mathematical
analysis, the data from the aforementioned system was tested
to see if it was truly random.
