Number-Phase Uncertainty Relation

概要

• 論文の詳細を見る

• Number-phase uncertainty relation is examined on the basis of an orthogonal phase state and a quasi-probability function. The measure of number fluctuation is not the usual standard deviation but a kind of Fisher information. This is a direct generalization to a discrete system of the corresponding quantity used recently by Hall in a theory of uncertainty for a coordinate-momentum system. It is essential to separate the "classical" part of a phase operator with the aid of the orthogonal phase state.
