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. WebTo this end we provide a characterization of when the Gorini-Kossakowski- Sudarshan-Lindblad (GKSL) equation de nes a proper generator when allowed ar- bitrary Lindblad operators (in particular, they need not be traceless as demanded by the GKSL Theorem).
