# Roy Glauber

Roy Glauber is the 2005 Nobel Prize for Physics. Deemed one of the founders of quantum optics for his theory of optical coherence, he introduced the Glauber correlators $g^{(n)}$, which are objects that we ourselves study a lot. His work is, therefore, of prime interest to our own.

Regarding the controversy with Sudarshan, it is true that Glauber took much formalism, ideas and theoretical results from the latter, but his interpretation of quantumness of the field turned out to be the correct one (at least the mainstream one), as opposed to that of Sudarshan who, along with Mandel and Wolf, had a much more classical understanding of the problem.
