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…
Generalizing Choi-like maps
Dariusz Chruściński, Marcin Marciniak, Adam Rutkowski
A problem of further generalization of generalized Choi maps acting on introduced by Cho, Kye and Lee is discussed. Some necessary conditions for posit…
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…
Paradoxical consequences of multipath coherence: perfect interaction-free measurements
Zhao Zhuo, Spandan Mondal, Marcin Markiewicz +4
Quantum coherence can be used to infer the presence of a detector without triggering it. Here we point out that, according to quantum mechanics, such interaction-free measurements…
