ABSTRACT Spontaneous Parametric Down-Conversion (SPDC), also known as parametric
fluorescence, parametric noise, parametric scattering and all various combinations of the …

Nonlinear optical effects have enabled numerous applications such as laser frequency
conversion, ultrafast electro-optical, and all-optical modulation. Both gaseous and bulk …

The technologies of heating, photovoltaics, water photocatalysis and artificial photosynthesis
depend on the absorption of light and novel approaches such as coherent absorption from a …

A protocol with the potential of beating the existing distance records for conventional
quantum key distribution (QKD) systems is proposed. It borrows ideas from quantum …

We demonstrate the generation of rubidium-resonant heralded single photons for quantum
memories. Photon pairs are created by cavity-enhanced down-conversion and narrowed in …

We report a bright photon-pair source with a coincidence counting rate per input power
(cps/mW) of tens of thousands, obtained via spontaneous four-wave mixing from a Doppler …

We report 100% duty cycle generation of sub-MHz single photon pairs at the rubidium D 1
line using cavity-enhanced spontaneous parametric downconversion. The temporal intensity …

We report on the experimental verification of quantum non-Gaussian character of a heralded
single-photon state with a positive Wigner function. We unambiguously demonstrate that the …

Normalized correlation functions provide expedient means for determining the photon-
number properties of light. These higher-order moments, also called the normalized factorial …

Spontaneous parametric down-conversion (SPDC) in a laser pumped optical nonlinear
medium can produce heralded single photons with a high purity but a very low yield …
