Coherence, quantum Fisher information, superradiance, and entanglement as interconvertible resources
Coherence, quantum Fisher information, superradiance, and entanglement as interconvertible resources
We demonstrate that quantum Fisher information and superradiance can be formulated as coherence measures in accordance with the resource theory of coherence, thus establishing a direct link between metrological information, superradiance and coherence. We also show that the trivial coherence measure has a metrological interpretation. The arguments are then generalized …
