Entanglement witnessing and quantum cryptography with non-ideal ferromagnetic detectors
Waldemar Kłobus, Andrzej Grudka, Andreas Baumgartner +3
We investigate theoretically the use of non-ideal ferromagnetic contacts as a mean to detect quantum entanglement of electron spins in transport experiments. We use a designated en…

When Are Popescu-Rohrlich Boxes and Random Access Codes Equivalent?
Andrzej Grudka, Karol Horodecki, Michał Horodecki +2
We study a problem of interconvertibility of two supra-quantum resources: one is so called PR-box, which violates CHSH inequality up to maximal algebraic bound, and second is so ca…
