Abstract: In this paper, we describe a single quantum resource to split the quantum information of arbitrary two-qubit. In addition, we discuss its hierarchical situation, so as to achieve more efficient and convenient information sharing. The… read more here.

DOI: 10.1088/1751-8121/acd500
Abstract: Robustness measures are increasingly prominent resource quantifiers that have been introduced for quantum resource theories such as entanglement and coherence. Despite the generality of these measures, their usefulness is hindered by the fact that some… read more here.

Abstract: Measurements invariably determine the physical state of a given ``observed system'' with respect to an ``observer system.'' This implies an inescapable two-body relationality upon which physical theories must rely. There has been a growing effort… read more here.

DOI: 10.1103/physrevlett.119.110503
Abstract: We derive a monogamy inequality for any local quantum resource and entanglement. It results from the fact that there is always a convex measure for a quantum resource, as shown here, and from the relation… read more here.
