For instance, both nitride NW-QDs and h-BN point defect based SPEs seem to exhibit photon entanglement. Which platform will provide stronger entanglement?
I suspect, that purity of the single photon that is emitted from either source will determine which source offers the best route for entanglement . Or perhaps I am wrong, i.e. none of these emitters (either based on InGaN QDs or h-BN point defects) producing entangled states. Could anyone of you please share your experience.
Entanglement involves more than one photon. For photon emitters it's described by resolving the shot noise distribution of the photons emitted. It's the shot noise distribution that describes the property that multiphoton states display Bose-Einstein statistics, which is what multiphoton state entanglement actually means.
Dear Saha,
The single photon entanglement (SPE) plays a key role for broad range of quantum devices, such as single photon emitters (SPEs), and applications, including quantum computation or flying qubits and quantum communications. Please refer to the following articles for more details about the physical processes underlying SPE in SPEs.
