Description
A notion of coherence vector of a general quantum state is introduced on the framework of quantum coherence resource theory [1]. This generalized
coherence vector completely characterizes the notions of being incoherent, as well as being maximally coherent. Moreover, using this notion and the majorization relation, a necessary condition for the conversion of general quantum states by means of incoherent operations is obtained. Finally, a new family of coherence monotones based on the coherence vector is introduced.
