Phys. Rev. Lett. 101, 170502 (2008) [4 pages]Entanglement Evolution in Finite DimensionsReceived 16 April 2008; published 21 October 2008 We provide a relation which describes how the entanglement of two d-level systems evolves as either system undergoes an arbitrary physical process. The dynamics of the entanglement turns out to be of a simple form and is fully captured by a single quantity. © 2008 The American Physical Society URL:
