Quantum and Classical Information and Entropy

Show Summary Details

Preview

Here it is shown that quantum systems can be understood as information processors. Information and entropy are related quantities but also different, since the first is formal whilst the second is dynamical. Both quantum and classical information acquisition are a three-step process that needs a processor, a regulator, and a decider.

Keywords: information acquiring; information selection; entropy; mutual information; processor; regulator; decider
