Temporal complementarity- single and two-photon interference

[San K]

I am looking for:

Any experiment/paper that shows -

complementarity between single- and two-photon interference (coherence and entanglement) in the Temporal domain.

On second thoughts this should be easy just use the same setup as in the spatial and create time delay between photons. I wonder why the authors did not do that. The OP concludes... perhaps such experiments have already been done.
