连续变量的互无偏基

Mutually Unbiased Bases for Continuous Variables

Stefan Weigert, Michael Wilkinson

摘要:

研究了N对连续变量的互无偏基的概念。对于与海森堡-外尔群相关的特定状态,要找到相互无偏的基,就归结为辛几何问题。给定一对连续变量,确定三个相互无偏的基地,而五个这样的基地表现出两对连续变量。对于N = 2,黄金比例出现在这些相互无偏的基础的定义中,这表明数论不仅在有限维环境中具有相关性。

英文摘要:

The concept of mutually unbiased bases is studied for N pairs of continuous variables. To find mutually unbiased bases reduces, for specific states related to the Heisenberg-Weyl group, to a problem of symplectic geometry. Given a single pair of continuous variables, three mutually unbiased bases are identified while five such bases are exhibited for two pairs of continuous variables. For N = 2, the golden ratio occurs in the definition of these mutually unbiased bases suggesting the relevance of number theory not only in the finite-dimensional setting.
