基于斜信息相干度量的量子不确定性关系

Quantum Uncertainty Relations Based on Skew Information Coherence Measure

  • 摘要: 量子相干性是一种重要的量子资源,与多个研究领域密切相关。基于斜信息的相干度量是一种在操作上和几何上均有效的相干性度量。本文研究了量子比特系统中基于斜信息的相干性的量子不确定性关系,针对三组一般测量基,根据它们的不相容性,推导出基于斜信息相干的量子不确定性关系,这种关系对于纯态而言是状态无关的。

     

    Abstract: Quantum coherence is an important quantum resource closely related to multiple research fields. The coherence measure based on skew information is valid both operationally and geometrically. We study the quantum uncertainty relations of skew information-based coherence in qubit systems. We derive the quantum uncertainty relations of the skew information-based coherence on three general measurement bases in terms of the incompatibility, which turns out to be state-independent for pure states.
