Coherence convertibility for mixed states
Xiaofei Qi, Zhaofang Bai, Shuanping Du
In this paper, by providing a class of coherence measures in finite dimensional systems, a sufficient and necessary condition for the existence of coherence transformations that co…
The Wigner-Yanase information can increase under phase sensitive incoherent operations
Shuanping Du, Zhaofang Bai
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…
Coherence measures and optimal conversion for coherent states
Shuanping Du, Zhaofang Bai, Xiaofei Qi
We discuss a general strategy to construct coherence measures. One can build an important class of coherence measures which cover the relative entropy measure for pure states, the…
Conditions for coherence transformations under incoherent operations
Shuanping Du, Zhaofang Bai, Yu Guo
We build the counterpart of the celebrated Nielsen's theorem for coherence manipulation in this paper. This offers an affirmative answer to the open question: whether, given two st…
Maximally coherent states
Zhaofang Bai, Shuanping Du
Relative entropy measure quantifying coherence, a key property of quantum system, is proposed recently. In this note, we investigate the maximally coherent state (MCS) with respect…
