We have several single photon sources, including nitrogen vacancy centers and quantum dots. Nobody has ever produced a "half-photon source" though.

- LeapingLennie 5y agoWhat would half-photons look like? I guess photons with half the energy expected given their wavelength and the Planck relation E = hc/λ?
- AnimalMuppet 5y agoNo, that's a complete photon, just one with a different wavelength. A half photon would have E = hc/2λ; that is, half the energy for the same wavelength.
