Qubit-qubit-qutrit quantum correlations in
Michał Banacki, Misaki Ohta, Abhyoudai S. Shaleena +5
We perform an extensive analysis of the quantum correlations carried by the qubit-qubit-qutrit pure state arising in the decay of a massive scalar into a fermion-antifermion pair a…
Unitary induced channels and Tsirelson's problem
Michał Banacki, Paweł Horodecki
Motivated by a recent progress concerning quantum commuting and quantum tensor models of composed systems we investigate a notion of (generalized) unitary induced quantum channel.…
No-signaling-proof randomness extraction from public weak sources
Ravishankar Ramanathan, Michał Banacki, Paweł Horodecki
The extraction of randomness from weakly random seeds is a topic of central importance in cryptography. Weak sources of randomness can be considered to be either private or public,…
Information backflow may not indicate quantum memory
Michal Banacki, Marcin Marciniak, Karol Horodecki +1
We analyze recent approaches to quantum Markovianity and how they relate to the proper definition of quantum memory. We point out that the well-known criterion of information backf…
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…
