What physical process determines the property of photon entanglement in a SPE?

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...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
