Construction of three qubit genuine entanglement with bi-partite positive partial transposes
Kil-Chan Ha, Seung-Hyeok Kye
We construct tri-qubit genuinely entangled states which have positive partial transposes with respect to bi-partition of systems. These examples disprove a conjecture [L. Novo, T.…
Construction of multi-qubit optimal genuine entanglement witnesses
Kyung Hoon Han, Seung-Hyeok Kye
We interpret multi-partite genuine entanglement witnesses as simultaneous positivity of various maps arising from them. We apply this result to multi-qubit {\sf X}-shaped Hermitian…
Various notions of positivity for bi-linear maps and applications to tri-partite entanglement
Kyung Hoon Han, Seung-Hyeok Kye
We consider bi-linear analogues of -positivity for linear maps. The dual objects of these notions can be described in terms of Schimdt ranks for tri-tensor products and Schmidt…
Three-qubit entanglement witnesses with the full spanning properties
Seung-Hyeok Kye
We construct three-qubit entanglement witnesses with the properties that all the partial transposes have the spanning properties. These witnesses determine faces for separable stat…
