Maximal intrinsic randomness of a quantum state

Year: 2024

Type: article

Abstract: Quantum states possess an intrinsic form of randomness, inaccessible even to an all-powerful eavesdropper. The authors find concise mathematical expressions for the maximal intrinsic randomness that can be extracted from any quantum state, as quantified by the conditional min-, von Neumann and max-entropies. They also characterize the optimal (and inequivalent) measurements in each case.
