Randomness: quantum versus classical
Recent tremendous development of quantum information theory led to a number of quantum technological projects, e.g., quantum random generators. This development stimulates a new wave of interest in quantum foundations. One of the most intriguing problems of quantum foundations is elaboration of a consistent and commonly accepted interpretation of quantum state. Closely related problem is clarif...
متن کاملQuantum Randomness and Nondeterminism
Does the notion of a quantum randomized or nondeterministic algorithm make sense, and if so, does quantum randomness or nonde-terminism add power? Although reasonable quantum random sources do not add computational power, the discussion of quantum random-ness naturally leads to several deenitions of the complexity of quantum states. Unlike classical string complexity, both deterministic and non...
متن کاملQuantum randomness and value indefiniteness
As computability implies value definiteness, certain sequences of quantum outcomes cannot be computable.
متن کاملQuantum Enhancement of Randomness Distribution
The capability of a given channel to transmit information is, a priori, distinct from its capability to distribute random correlations. Despite that, for classical channels, the capacity to distribute information and randomness turns out to be the same, even with the assistance of auxiliary communication. In this work we show that this is no longer true for quantum channels when feedback is all...
متن کاملQuantum mechanics and algorithmic randomness
A long sequence of tosses of a classical coin produces an apparently random bit string, but classical randomness is an illusion: the algorithmic information content of a classically-generated bit string lies almost entirely in the description of initial conditions. This letter presents a simple argument that, by contrast, a sequence of bits produced by tossing a quantum coin is, almost certainl...
