Title:         Kondo Physics from a Quantum Information Perspective


Abstract:
A characterization of a Kondo system using only entanglement measures is
provided.  For this purpose:  I shall firstly analyze a spin realization 
of the
single channel Kondo model and show how one can determine the Kondo
screening length by a measure of entanglement.  I then show how the 
entanglement
with the impurity "stored" in the Kondo cloud may be used to generate 
distance
independent long range entanglement between the end point of a Kondo 
spin chain.
