Abstract

We demonstrate, using an all-optical setup, the difference between local and global dynamics of entangled quantum systems coupled to independent environments. Even when the decay of each system is asymptotic, quantum entanglement may suddenly disappear. We also demonstrate experimentally that measurements performed in the environment affects the local evolution.
