Strictly incoherent operations for one-qubit systems
Shuanping Du, Zhaofang Bai
Strictly incoherent operations (SIO) proposed in [Phys. Rev. Lett. 116, 120404 (2016)] are promising to be a good candidate of free operations in the resource theory of quantum coh…
Coherent preorder of quantum states
Zhaofang Bai, Shuanping Du
As an important quantum resource, quantum coherence play key role in quantum information processing. It is often concerned with manipulation of families of quantum states rather th…
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…
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…
The automatic additivity of Lie derivations on von Neumann algebras
Zhaofang Bai, Shuanping Du, Yu Guo
Let be a von Neumann algebra with no central summands of type I. It is shown that every nonlinear Lie derivation () on is an additive d…
