DESCRIPTION:Environment Induced Decoherence is a physical concept which gi
 ves a dynamical explanation to the disappearance of quantum phenomenon in 
 the real world. In a few words\, it states that a quantum system is never 
 isolated so that quantum correlations disappear due to the action of the e
 nvironment on the system. Focusing on finite-dimensional quantum systems u
 ndergoing Markovian evolutions\, we show how the usual non-commutative Poi
 ncare and log-Sobolev inequalities can be adapted in order to capture the 
 speed of decoherence.
