It is shown that the anticorrelations in the photon numbers of the signal and the idler wave, respectively, generated in parametric three‐wave interaction under suitable conditions, violate an inequality well‐known in classical communication theory. Hence, it must be concluded that these anticorrelations reflect a typical quantum mechanical feature of light. In fact, this nonclassical behaviour is responsible for the occurrence of photon antibunching in the superposition field made up of both the signal and the idler wave, as will be pointed out in some detail.
