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…
