Abstract

In this paper, we build some uncertainty relations for arbitrary N quantum channels based on the Wigner–Yanase skew information. It is shown that our lower bounds are stronger than the ones proposed by Zhang et al (2021 Phys. Lett. A 387 127029; 2021 Laser Phys. Lett. 18 095204) respectively in all intervals. In particular, we derive several uncertainty relations for N unitary channels. Moreover, we establish several descending sequences of lower bounds for the uncertainty relations of N quantum channels. Detailed examples are provided.

基于 Wigner-Yanase 偏斜信息的 N 量子信道的更严格不确定性关系

本文基于 Wigner-Yanase 偏斜信息，为任意 N 量子信道建立了一些不确定性关系。结果表明，我们的下界在所有区间都比 Zhang 等人提出的下界（2021 Phys.特别是，我们推导出了 N 个单元信道的若干不确定性关系。此外，我们还为 N 个量子信道的不确定性关系建立了若干降序下界。我们还提供了详细的例子。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
