23.12 Chemistry of quantum entanglement dynamics
Considering multipartite entanglement as a chemical compound opens a new view on the entanglement dissipative evolution. In fact, the particles of environment represent nothing else but the solvent in which the entanglement compound dissociates! The solvent can act on the whole compound (global quantum noise) or particular elements of the compound (local quantum noise). The differences between these two mechanisms are in the presense of clustering stages in the case of global noise, when particles reassemble to form almost equal bipartitions, tripartions, etc.

30.09 Feasible coupling of two superconducting resonators by a single trapped atom
We present a theoretical proposal how to couple (selectively) microwave radiation in two superconducting resonators via the Raman effect for an ion trap.
