Experimentally feasible semi-device-independent certification of outcome POVMs
Piotr Mironowicz, Marcin Pawłowski
In this paper we construct a semi-device-independent protocol able to certify the presence of the generalized measurements. We show robustness of the protocol and conclude that it…
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…
Semi-Device Independent Quantum Money
Karol Horodecki, Maciej Stankiewicz
The seminal idea of quantum money not forgeable due to laws of Quantum Mechanics proposed by Stephen Wiesner, has laid foundations for the Quantum Information Theory in early '70s.…
Hilbert-Schmidt distance and entanglement witnessing
Palash Pandya, Omer Sakarya, Marcin Wieśniak
Gilbert proposed an algorithm for bounding the distance between a given point and a convex set. In this article we apply the Gilbert's algorithm to get an upper bound on the Hilber…
Thermal Processes and State Achievability
Paweł Mazurek
A complete characterization of the set of states that can be achieved through Thermal Processes (TP) is given by describing all vertices, edges and facets of the allowed set of sta…
Multiple-shot and unambiguous discrimination of von Neumann measurements
Zbigniew Puchała, Łukasz Pawela, Aleksandra Krawiec +2
We present an in-depth study of the problem of multiple-shot discrimination of von Neumann measurements in finite-dimensional Hilbert spaces. Specifically, we consider two scenario…
