WebSudarshan's most significant work may have been his contribution to the field of quantum optics. His theorem proves the equivalence of classical wave optics to quantum optics. The theorem makes use of the Sudarshan representation. This representation also predicts optical effects that are purely quantum, and cannot be explained classically. Webthe GKSL equation have been researched[10, 28–31]. For such open quantum systems, Hasegawa [32] derived a KUR by exploiting the Mandelstam-Tamm speed limit [33, 34]. In this KUR, a dynamical activity-like quantity appeared instead of F. We point out that this quantity equals the SLD Fisher information when Hamiltonian
