Coherence measures and optimal conversion for coherent states
Shuanping Du, Zhaofang Bai, Xiaofei Qi · Quantum Information and Computation · 2015
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 l1-norm measure for pure states and the α-entropy measure. The optimal conversion of coherent states under incoherent operations is presented which sheds some light on the coherence of a single copy of a pure state.
