Note on the Margolus-Levitin quantum speed limit for arbitrary fidelity
Krzysztof Andrzejewski, Katarzyna Bolonek-Lasoń, Piotr Kosiński
For vanishing fidelity between initial and final states two important quantum speed limits, the Mandelstam-Tamm limit (involving energy dispersion) and Margolus-Levitin one (involv…

Bell inequalities for group: classical and quantum bounds for two orbits case
Katarzyna Bolonek-Lason, Piotr Kosinski
Within Guney-Hillery approach a number of examples of classical and quantum bounds on sum of probabilities resulting from two orbits of is considered. It is shown that the vi…
