Accordingly, our results reveal that the relationship between them depends on the diagonal elements of density matrix in an arbitrary two-qubit X-state. ![]() As analytical examples, we consider five simple cases in which we examine the relationship between the uncertainty bound and quantum coherence. In this work, we explore quantum-memory-assisted entropic uncertainty bound and quantum coherence for an arbitrary two-qubit X-state, and then we get analytically an explicit relation between them. ![]() On the other hand, quantum coherence is an important physical resource for quantum tasks. Abstract: By considering one of the particles as a memory in a two-particle system, the entropic uncertainty relation can be improved and it is called quantum-memory-assisted entropic uncertainty relation. ![]()
