Environment Induced Decoherence is a physical concept which gives 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 environment on the system. Focusing on finite-dimensional quantum systems undergoing Markovian evolutions, we show how the usual non-commutative Poincare and log-Sobolev inequalities can be adapted in order to capture the speed of decoherence.
