Harnessing the power of quantum mechanics to generate true and unique, high-speed random numbers.

Quantum random numbers from the vacuum

While a coin toss or the casting of a die may seem random, short-term behaviour is very predictable when for example observed with high speed cameras. Software algorithms offer “randomness” as well. However, the randomness of a deterministic program (software) can only be as random as its initial seed value. A logical step are physical random number generators, which rely on measuring the noise of a physical process (like the thermal noise of a resistor) to produce randomness. While this might seem intuitive, it is far from ensured that these numbers are indeed truly random and thus uncorrelated with a 3rd party that possibly has more knowledge about the physical system.

The only true randomness can be found in quantum mechanics. The randomness emanates from its intrinsic statistical nature and is for example deeply linked to Heisenberg’s uncertainty principle.
