Interpolating between positive and completely positive maps: a new hierarchy of entangled states
arXiv:2104.13829 · doi:10.3390/e23050625
Abstract
A new class of positive maps is introduced. It interpolates between positive and completely positive maps. It is shown that this class gives rise to a new characterization of entangled states. Additionally, it provides a refinement of the well-known classes of entangled states characterized in term of the Schmidt number. The analysis is illustrated with examples of qubit maps.
