We report on a source of ultranarrow-band photon pairs generated by widely
nondegenerate cavity-enhanced spontaneous down-conversion. The source is designed to …

We observe narrow band pairs of time-correlated photons of wavelengths 776 and 795 nm
from nondegenerate four-wave mixing in a laser-cooled atomic ensemble of Rb 87 using a …

Emission and absorption of single photons by single atoms is a fundamental limit of matter–
light interaction, manifesting its quantum mechanical nature. As a controlled process, it is …

The generation of ultra-narrowband, pure and storable single photons with widely tunable
wave shape is an enabling step toward hybrid quantum networks requiring interconnection …

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 review the field of Optical Quantum Computation, considering the various
implementations that have been proposed and the experimental progress that has been …

We demonstrate an ultrabright, narrow-band and frequency-tunable photon-pair source
based on cavity-enhanced spontaneous parametric down conversion (SPDC) which is …

Linear optical circuits of growing complexity are playing an increasing role in emerging
photonic quantum technologies. Individual photonic devices are typically described by a …

In this paper we study photon pairs generated in a nonlinear cavity composed of a nonlinear
crystal surrounded by mirrors, by the process of spotaneous parametric downconversion …

A quantum network combines the benefits of quantum systems regarding secure information
transmission and calculational speed-up by employing quantum coherence and …
