摘要
Bohr proposed that the outcome of a measurement becomes objective and real, and, hence, classical, when its results can be communicated by classical means. In this work we revisit Bohr's postulate using modern tools from 量子 資訊 theory. We find a full confirmation of Bohr's idea: if a measurement device is in a nonclassical state, the measurement results cannot be communicated perfectly by classical means. In this case some part of the 資訊 in the measurement apparatus is lost in the process of communication: the amount of this lost 資訊 turns out to be the 量子 discord. The 資訊 loss occurs even when the apparatus is not entangled with the system of interest. The tools presented in this work allow us to generalize Bohr's postulate: we show that for pure system-apparatus states 量子 communication does
