Photon number resolution is important for a wide range of applications. Conventional techniques for photon number resolution are prohibitively expensive. However, schemes which are easier to implement can be found when the single shot criterion for detection is relaxed. In this poster, we show a simple linear optical scheme which can discriminate between various Fock state inputs. We compare two measurement strategies: coincidence measurements and homodyne detection. We find the minimum number of trials needed to discriminate between various Fock states.
