Pulsed states of light are relevant for the implementation of quantum optics and quantum information protocols. To this aim, a full characterization of the optical states is needed.

In principle, two detection strategies exist: the optical homodyne detection technique gives access to the wave-like properties of light, while the direct detection technique based on photon-number-resolving detectors is used to explore the particle-like features.

This project targets the implementation of a new hybrid detection scheme capable of merging the two technologies.

Two different classes of detectors, namely the hybrid photodetectors and the Si-photomultipliers, will be considered and compared. The ultimate goal of the project is the exploitation of the new detection scheme in testing specific quantum states of light and in realizing a coherent-state-discrimination protocol.
