Uncertainty principle certifies genuine source of intrinsic randomness    [PDF]

Manik Banik, Trina Chakraborty, Pinaki Patra

The Born's rule introduces intrinsic randomness to the outcomes of a measurement performed on a quantum mechanical system. But Born's rule, alone, can not guarantee the generation of intrinsic randomness for arbitrarily prepared state of a given system. In contrast to this, here we show that uncertainty principle can do so, not only in quantum mechanics but for any probabilistic theory. Also the minimum amount of intrinsic randomness that can be guaranteed for arbitrarily prepared state of the system is quantified by the amount of (un)certainty.
