Construction of exposed indecomposable positive linear maps between matrix algebras

Kil-Chan Ha, Seung-Hyeok Kye

We construct a large class of indecomposable positive linear maps from the $2 \times 2$ matrix algebra into the $4 \times 4$ matrix algebra, which generate exposed extreme rays of th…

Multi-partite separable states with unique decompositions and construction of three qubit entanglement with positive partial transpose

Kil-Chan Ha, Seung-Hyeok Kye

We investigate conditions on a finite set of multi-partite product vectors for which separable states with corresponding product states have unique decomposition, and show that thi…
