Hyperentanglement in Parametric Down-Conversion
A theory of spontaneous parametric down-conversion, which gives rise to a quantum state that is simultaneously entangled in three-dimensional wavevector and polarization, allows us to understand the unusual characteristics of fourth-order quantum interference in many experiments, including ultrafast parametric down-conversion, the speci c example illustrated in this paper. The comprehensive app...
متن کاملQuantum properties of backward parametric down - conversion
Backward parametric down-conversion, in which one of the twin beams is generated in the opposite direction with respect to the pump laser source (Fig.1a), was theoretically predicted fifty years ago, but only recently became experimentally accessible [1], due the challenges involved in the fabrication of the required submicrometer poling period. A peculiarity of this geometry is the presence of...
متن کاملParametric down conversion of X-ray photons.
Parametric down conversion of X-ray photons in diamond crystals was detected in two experiments, both using the phase-matching scheme first employed in the X-ray regime by Eisenberger & McCall [Phys. Rev. Lett. (1971), 26, 684-688]. The conversion events were detected by a combination of time-correlation spectroscopy and energy discrimination, using Si drift-chamber detectors. The time-correlat...

متن کاملPhotonic Crystal Waveguides for Parametric Down-conversion
Photonic crystals create dramatic new possibilities for nonlinear optics. Line defects are shown to support modes suitable for the production of pairs of photons by the material’s second order nonlinearity even if the phase-matching conditions cannot be satisfied in the bulk. These structures offer the flexibility to achieve specific dispersion characteristics and potentially very high brightne...
