"True' randomness cannot be generated by any efficient algorithm (Kolmogorov) while pseudorandomness can be, such as the apparently random digit sequences of irrational numbers. The experimental realization of quantum states is taken to be an example of 'true' randomness in nature. However, if there is a deterministic substratum to such outcomes, then there apparently would be no 'true' randomness' in nature.(adsbygoogle = window.adsbygoogle || []).push({});

The following paper claims experimental evidence for 'true' randomness in quantum outcomes in the Kolmogorov sense. Since the authors concede they cannot 'prove' true randomness, would this evidence carry weight to those who hold that an underlying deterministic substratum must exist?
