Is absolute separability determined by the partial transpose?
The absolute separability problem asks for a characterization of the quantum states ρ ∈ Mm ⊗Mn with the property that UρU† is separable for all unitary matrices U. We provide evidence that ρ is absolutely separable if and only if UρU† has positive partial transpose for all unitary matrices U. In particular, we show that many well-known separability criteria are unable to detect entanglement in ...
متن کاملPartial Transpose of Permutation Matrices
The main purpose of this paper is to look at the notion of partial transpose from the combinatorial side. In this perspective, we solve some basic enumeration problems involving partial transpose of permutation matrices. Specifically, we count the number of permutations matrices which are invariant under partial transpose. We count the number of permutation matrices which are still permutation ...

متن کاملDistillability via protocols respecting the positivity of partial transpose.
We show that all quantum states that do not have a positive partial transpose are distillable via channels, which preserve the positivity of the partial transpose. The question whether bound entangled states with non-positive partial transpose exist is therefore closely related to the connection between the set of separable superoperators and positive partial transpose-preserving maps.
