Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids.

The most common way to create entangled photons is by a process known as Spontaneous Parametric Down Conversion (SPDC) which involves a single photon being split into two entangled photons of ...

We directly generate three entangled photons using the nonlinear process of cascaded spontaneous parametric downconversion (C-SPDC; ref. 13).In downconversion, a pump photon, with frequency ω p ...

Generating entangled photons with nonlinear metasurfaces ... (SPDC) which involves a single photon being split into two entangled photons of lower frequencies, known as the signal and idler.

Quantum entanglement between photons is being explored extensively by physicists, often with the aim of developing new quantum technologies for computing, communication, sensing and imaging. Some ...

The spatially entangled near-infrared (810 nm) photons, produced after passing through the NLC, were then detected using another lens and the EMCCD. This SPDC process produces an encoded image of a ...
