# Time-resolved two-photon quantum interference

@article{Legero2003TimeresolvedTQ, title={Time-resolved two-photon quantum interference}, author={Thomas Legero and Tatjana Wilk and A. G. Kuhn and Gerhard Rempe}, journal={Applied Physics B}, year={2003}, volume={77}, pages={797-802} }

The interference of two independent single-photon pulses impinging on a beam splitter is analysed in a generalised time-resolved manner. Different aspects of the phenomenon are elaborated using different representations of the single-photon wave packets, like the decomposition into single-frequency field modes or spatio-temporal modes matching the photonic wave packets. Both representations lead to equivalent results, and a photon-by-photon analysis reveals that the quantum-mechanical two… Expand
