Abstract
Classical optical interference experiments correspond to a measurement of the first-order correlation function of the electromagnetic field. The converse of this statement: experiments that measure the first-order correlation functions do not distinguish between the quantum and classical theories of light, does not always hold. A counterexample is given.
