Single photons are the carrier of choice in many quantum information processing protocols. Encoding information in a high-dimensional Hilbert space allows for the transfer of more than one bit of information per photon. We use a spatial light modulator (SLM) to direct the single photons to distinct positions of a virtual grid in the Fourier plane of the SLM. An electron-multiplying CCD (EMCCD) was used to detect the position of the photon at the receiver side. After analyzing the data, we conclude that, in contrast to an intensified CCD (ICCD), an EMCCD is not suited to detect the position of one single photon impinging on the camera in a single-shot measurement.
