the three- and four-wave mixing (χ(2)andχ(3)) effects have been extensively studied, especially in the micro-/nano-structures by which the photon-photon interaction strength is greatly enhanced. So far, the
Phase matching is shown to provide a tunable gate that helps discriminate entangled states of light generated by four-wave mixing (FWM) in optical fibers against uncorrelated photons originating from Raman scattering. Two types of such gates are discusse
These biphotons are naturally energytime entangled because of energy conservation in the generation process. Therefore, we measure the two-photon temporal waveform and spectral correlation and confirm the Einstein-Podolsky- Rosen energy-time entanglement, which plays an essential role in quantum ...

In such a hybrid sys- tem, some fascinating quantum phenomena have been demonstrated, such as microwave- optical conversion and entanglement [11, 12], atom-magnon entanglement [13], Fano- type optical response and four-wave mixing process [14], and phonon-magnon-photon entanglement [15]. ...
A quantum description of propagating-wave nonlinear optics is reviewed, and the formalism is applied to the common nonlinear optical processes that are used in quantum optics: spontaneous parametric downconversion and four-wave-mixing. The tailoring of photonic entanglement is crucial for a number of ...
processhigherordernonclassicalityPossibilities of generation of lower order and higher order intermodal entanglement in four‐wave mixing (FWM) process are rigorously investigated using Sen‐Mandal perturbative technique. The investigation has revealed that for a set of experimentally realizable parameters, ...
U'Ren1 We have designed and implemented a photon-pair source, based on the spontaneous four wave mixing (SFWM) process in a few-mode fiber, in a geometry which permits multiple, simultaneous SFWM processes, each associated with a distinct combination of transverse modes for the four ...
Entangled quantum states in high-dimensional space show many advantages compared with entangled states in two-dimensional space. The former enable quantum communication with higher channel capacity, enable more efficient quantum-information processing an
