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.…
On steering in the C*-algebraic framework
Michal Banacki
We discuss a scenario of bipartite steering with local subsystems of the parties modeled by certain operator algebras. In particular, we formalize the notion of quantum assemblages…
Multipartite channel assemblages
Michał Banacki, Ravishankar Ramanathan, Paweł Horodecki
Motivated by the recent studies on post-quantum steering, we generalize the notion of bipartite channel steering by introducing the concept of multipartite no-signaling channel ass…
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,…
Hybrid no-signaling-quantum correlations
Michał Banacki, Piotr Mironowicz, Ravishankar Ramanathan +1
Fundamental investigations in non-locality have shown that while the no-signaling principle alone is not sufficient to single out the set of quantum non-local correlations, local q…
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…
On the edge of the set of no-signaling assemblages
Michał Banacki, Ricard Ravell Rodríguez, Paweł Horodecki
Following recent advancements, we consider a scenario of multipartite postquantum steering and general no-signaling assemblages. We introduce the notion of the edge of the set of n…
Single trusted qubit is necessary and sufficient for quantum realisation of extremal no-signaling correlations
Ravishankar Ramanathan, Michał Banacki, Ricard Ravell Rodríguez +1
Quantum statistics can be considered from the perspective of postquantum no-signaling theories in which either none or only a certain number of quantum systems are trusted. In thes…
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…
Quantum symmetry groups of noncommutative tori
Michal Banacki, Marcin Marciniak
We discuss necessary conditions for a compact quantum group to act on the algebra of noncommutative -torus in a filtration preserving way in the sense of Banica…
