Phys. Rev. A 74, 034301 (2006) [3 pages]Generalization of the Margolus-Levitin boundReceived 19 May 2006; published 11 September 2006 The Margolus-Levitin lower bound on the minimal time required for a state to be transformed into an orthogonal state is generalized. It is shown that for some initial states the new bound is stronger than the Margolus-Levitin one. © 2006 The American Physical Society URL:
