On propose une methode de matrice de transfert amelioree pour calculer la fonction de partition des systemes de spins quantiques, qui est exprimee par le Mieme approximant de la transformation de Suzuki-Trotter a nombre de Trotter M. Le point est d'incorporer la propriete de symetrie du sous-systeme de Trotter dans les calculs. La thermodynamique est decrite par la valeur propre maximum de la matrice de transfert
