Hybrid quantum network design against unauthorized secret-key generation, and its memory cost
Omer Sakarya, Marek Winczewski, Adam Rutkowski +1
A significant number of servers that constitute the Internet are to provide private data via private communication channels to mutually anonymous registered users. Such are the ser…
A Class of PPT Entangled States Arbitrary Far From Separable States
Adam Rutkowski, Michał Studziński
In this paper we show an explicit construction of multipartite class of entangled states with the PPT (Positive Partial Transposition) property in every cut. We investigate propert…
Necessary and sufficient condition of separability for D-symmetric diagonal states
Adam Rutkowski, Michal Banacki, Marcin Marciniak
For multipartite states we consider a notion of D-symmetry. For a system of qubits it concides with usual permutational symmetry. In case of qudits () the D-symmet…
Unified approach to geometric and positive-map-based non-linear entanglement identifiers
Marcin Markiewicz, Adrian Kolodziejski, Zbigniew Puchala +3
Detecting quantumness of correlations (especially entanglement) is a very hard task even in the simplest case i.e. two-partite quantum systems. Here we provide an analysis whether…
A family of generalized Horodecki-like entangled states
Dariusz Chruściński, Adam Rutkowski
We provide a multi-parameter family of 2-qudit PPT entangled states which generalizes the celebrated Horodecki state in 3 x 3. The entanglement of this family is identified via sem…
