Abstract

Experts have said: “...it seems fair to say that the study of entanglement is in its infancy, ... it is not entirely clear what... can be expected as a result of the study of quantitative measures of entanglement.” In an ideal world, entanglement of small and isolated quantum systems would be stable and uncorrupted. But in reality no physical system can be isolated completely. We will discuss the qualitatively and quantitatively surprising effects that weak noise can have on entangled pairs of quantum objects, even when they relax individually very slowly.
