Spontaneous parametric down-conversion (SPDC) has been a key enabling technology in exploring quantum phenomena and their applications for decades. For instance, traditional SPDC, which splits a high-energy pump photon into two lower-energy photons, is a

The measurement of the position–momentum Einstein–Podolsky–Rosen (EPR) correlations of a two-photon state is important for many quantum information applications ranging from quantum key distribution to coincidence imaging.

The Source of Time-Correlated Photons at 1.064 μm and its Applications
The source of time-correlated photon-pairs at 1064 nm is described. The source consists of the spontaneous parametric down-conversion (SPDC) generator, pumped by cw laser operating at 532 nm, and the measuring and control appliances.

Single GaAs Nanowires for Near-Infrared Spontaneous Parametric Down-Conversion
International audienceWe report 60 GHz/Wm photon pair generation via type-0 spontaneous parametric down-conversion at 1550 nm from individual free-standing GaAs nanowires with sub-450 nm diameter and lengths up to 5 ...

Polarization-Angle SPDC Spectrum and its Effect on Generated Photon States
Analytical formulas for vector components of the polarization vector of spontaneous parametric down-conversion (SPDC) radiation in the degenerated regime and its dependencies on the angle between the principal sections for the pump and SPDC rays are ...

We develop a nonperturbative formulation based on the Green's function quantization method that can describe spontaneous parametric down-conversion in the high-gain regime in nonlinear optical structures with arbitrary amount of loss and dispersion. This

Mie resonances in the spectrum of spontaneous parametric down-conversion
Paper FTh1O.5We report on the first-time generation of biphotons via spontaneous parametric down-conversion driven by Mie-type resonances in subwavelength metasurfaces.

Multi-qubit production in spontaneous parametric down conversion [PDF]
We present a novel yet simple approach to produce multiple entangled photon pairs through spontaneous parametric down conversion (SPDC). We have designed Gaussian masks to subdivide the pump beam before passing it through a nonlinear medium. In this way, we are able to observe simultaneous separate down converted emission cones with spatial overlap ...

Understanding High-Gain Twin-Beam Sources Using Cascaded Stimulated Emission
We present a new method for the spectral characterization of pulsed twin-beam sources in the high-gain regime, using cascaded stimulated emission. We show an implementation of this method for a periodically poled potassium titanyl phosphate spontaneous ...
