“…[20] for spectral factorizability in photon pair states. Thus, we reach the important conclusion that factorable two photon states [13,20,21,23] lead to Fourier transform limited heralded single photons. Let us note that the latter route involves no filtering, and therefore can lead to bright, broadband sources of FT-limited single photons.…”

Generation of Fourier-transform-limited heralded single photons

In this paper we study the spectral (temporal) properties of heralded single photon wavepackets, triggered by the detection of an idler photon in the process of parametric downconversion. The generated single photons are studied within the framework of the chronocyclic Wigner function, from which the single photon spectral width and temporal duration can be computed. We derive specific conditions on the two-photon joint spectral amplitude which result in both pure and Fouriertransform limited heralded single photons. Likewise, we present specific source geometries which lead to the fulfilment of these conditions and show that one of these geometries leads, for a given pump bandwidth, to the temporally shortest possible heralded single photon wavepackets.

Demonstration of the three-photon de Broglie wavelength by projection measurement

Two schemes of projection measurement are realized experimentally to demonstrate the de Broglie wavelength of three photons without the need for a maximally entangled three-photon state (the NOON state). The first scheme is based on the proposal by Wang and Kobayashi (Phys. Rev. A 71, 021802) that utilizes a couple of asymmetric beam splitters while the second one applies the general method of NOON state projection measurement to three-photon case. Quantum interference of three photons is responsible for projecting out the unwanted states, leaving only the NOON state contribution in these schemes of projection measurement.

“…Entangled two-photon states with coincident frequencies have been obtained using extended phase-matching conditions, i.e. assuming groupvelocity phase matching on the top of the usual phase matching [20,21,22]. Such states have perfect visibility in the usual interferometric setups and moreover allow a very precise clock synchronization [23].…”

A nonlinear planar waveguide pumped by a beam orthogonal to its surface may serve as a versatile source of photon pairs. Changing pump-pulse duration, pump-beam transverse width, and angular decomposition of pump-beam frequencies characteristics of a photon pair including spectral widths of signal and idler fields, their time durations as well as degree of entanglement of two fields can be changed significantly. Using the measured spectral widths of the down-converted fields and width of a coincidence-count dip in a Hong-Ou-Mandel interferometer entropy of entanglement can be determined.
