Quantum optics is concerned with the distribution of photons in optical modes. Classical models of photon statistics place restrictions on the properties of these distributions. Certain optical states exhibit photon statistics that violate these classical conditions, such as photon anti-bunching in single-mode states, and joint photon-number correlations in two-mode states. While correlation in measurement outcomes on two-mode optical states is welldocumented, we have developed a scheme to show

... discorrelation -the propensity of measurement outcomes to never be equal. Using coherent states, single photons and projective measurement, we show how the probability of measuring the same photon number on each mode of a two mode state is strictly zero.
