Counting the number of photons in an electromagnetic mode is an important tool for quantum information processing. In order to perform a single shot measurement, one usually encodes information about the photon number into a qubit state and read out the qubit. Repeating this procedure while varying the encoded single bit of information enables to pinpoint the number of photons. In this talk, I will present two experiments that address two main challenges in photocounting.
