  Observation of the purely quantum mechanical effects of quasi-classical
states is of utmost importance since these states are realistic sources of
radiation and do not have any shortage in photon numbers. Therefore, they do
not face the scalability problem as much as other single-photon sources do,
which makes them much more robust against photon loss. Moreover, these states
define the standard quantum limit. Hence, finding their quantum signature hints
to the highest possible single-photon rate. In this manuscript, we attempt to
demonstrate this idea theoretically using known dynamics and then present
supporting experimental results. Through our experiment, we realize two-photon
bunching from the transfer of quantum information using such states with the
projection of orbital angular momentum from a continuous wave source. Our work
is a step forward towards a more diverse and practical use of quasi-classical
states in the domain of quantum optics and quantum information.
