The Wigner-Yanase information can increase under phase sensitive incoherent operations
arXiv:1505.00151 · doi:10.1016/j.aop.2015.04.023
Abstract
We found that the Wigner-Yanase skew information, which has been recently proposed as a measure of coherence in [Phys. Rev. Lett. \textbf{113}, 170401(2014)], can increase under a class of operations which may be interpreted as incoherent following the framework of Baumgratz et al., while being phase sensitive.
