Entanglement evolution in finite dimensions
arXiv:0804.0208 · doi:10.1103/PhysRevLett.101.170502
Abstract
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.
