Entanglement Cost for Sequences of Arbitrary Quantum States

Quantum Physics 2011-01-07 v3

Abstract

The entanglement cost of arbitrary sequences of bipartite states is shown to be expressible as the minimization of a conditional spectral entropy rate over sequences of separable extensions of the states in the sequence. The expression is shown to reduce to the regularized entanglement of formation when the n-th state in the sequence consists of n copies of a single bipartite state.
