One of the main assumptions that goes into its derivation, and that makes it easily solvable is the as-sumption of Markovianity or being ‘memoryless’. This 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.
