TL;DR: It is proved that, for any coherent state, there are examples of subchannel discrimination problems such that this coherent state allows for a higher probability of successfully discriminating subchannels than that of all incoherent states, which provides an operational interpretation of the maximum relative entropy of coherence.

TL;DR: It is established in particular that any resource state enables an advantage in a channel discrimination task, allowing for a strictly greater success probability than any state without the given resource.

TL;DR: This work analyzes, from a resource-nonspecific standpoint, the optimal efficiency of resource formation and distillation tasks with only a single copy of the given quantum state, thereby establishing a unified framework of one-shot quantum resource manipulation.

TL;DR: In this article, the authors study cohering power, the ability of quantum operations to produce coherence, and decompose a generic quantum operation into three basic operations, namely, unitary, appending and dismissal operations, and show that the coherence of any quantum operation is upper bounded by the corresponding unitary operation.

TL;DR: In this article, a set of tools applicable to broad classes of resource theories is developed, revealing the similarities among many of them and establishing universal limitations on the distillation of such resources in practical settings.
