“…The Hong-Ou-Mandel effect, however, solely relies on the statistics of the involved particles and is therefore at the very heart of quantum optics per se. To date, photon pairs can be routinely sent through optical fibers [5], and-due to the rapid progress in the fabrications of nano-photonic components-integrated optical waveguiding structures on silicon chips are very promising candidates towards more complicated networks of multimode interference devices [6]. Furthermore, in the realm of optical metamaterials, the measurement of the Hong-Ou-Mandel dip for magnetic plasmon waves has been reported recently [7].…”

Abstract:The Hong-Ou-Mandel effect is studied in the context of twophoton transport in a one-dimensional waveguide with a single scatterer. We numerically investigate the scattering problem within a time-dependent, wave-function-based framework. Depending on the realization of the scatterer and its properties, we calculate the joint probability of finding both photons on either side of the waveguide after scattering. We specifically point out how Hong-Ou-Mandel interferometry techniques could be exploited to identify effective photon-photon interactions which are mediated by the scatterer. The Hong-Ou-Mandel dip is discussed in detail for the case of a single two-level atom embedded in the waveguide, and dissipation and dephasing are taken into account by means of a quantum jump approach.

Entanglement swapping at 1550 nm was experimentally demonstrated based on two polarization-entangled photon pairs, which were created in two independent PPLN waveguides. Mandel dip was measured by using fourfold coincidences to yield a visibility of 71.8% and verify quantum interference between photons from two separated sources. By making Bell-state measurement, the two initially independent photons were projected into an entanglement state. An interference visibility of 37.5% was observed for these two photons indicating the entanglement state was successfully swapped by using polarization-entangled photon pairs in the telecom band.

“…Our scheme uses timebin entangled photons, which are pulsed entangled states suitable for high-clock-rate systems, generated by spontaneous four-wave mixing (SFWM) in dispersion shifted fibers (DSF) [15,16,17,18,19]. As previously demonstrated in the short wavelength band [20] and the 1.5-μm band [21], the fiber-based sources facilitated the generation of indistinguishable photon pairs. Also, the use of high-speed InGaAs APDs with a 500-MHz gate frequency, which were realized using the sine-wave gating technique [22], contributed significantly to the increase in the fourfold count rate.…”

We report the first entanglement swapping experiment using entangled photon-pair sources based on spontaneous four-wave mixing (SFWM). The 1.5-μm band entangled photon pairs generated by SFWM in two independent 500-m dispersion shifted fibers exhibited quantum interference, thanks to the negligible walk-off between the pump and photon pairs. The use of 500-MHz gated-mode InGaAs/InP avalanche photodiodes based on the sine-wave gating technique increased the fourfold coincidence rate significantly. As a result, the formation of an entanglement between photons from independent sources was successfully observed.
